NAME

       myproxy-server.config - myproxy-server configuration file

DESCRIPTION

The myproxy-server.config file sets the policy for the myproxy-server(8), specifying what credentials may
be stored in the server's repository, who is authorized to retrieve credentials, and other configurable
server behaviors. By default, the myproxy-server(8) looks for this file in /etc/myproxy-server.config
and if it is not found there, it looks in $GLOBUS_LOCATION/etc/myproxy-server.config. A template is
provided at $GLOBUS_LOCATION/share/myproxy/myproxy-server.config. The myproxy-server -c option can be
used to specify an alternative location.

The following lines set access control policies according to the client's certificate subject
distinguished name (DN). Note that MyProxy uses non-standard regular expressions for distinguished name
(DN) matching. See the REGULAR EXPRESSIONS section below for details.

accepted_credentials “DN regex”
Each of these lines allows any clients whose DNs match the given limited regex to connect to the
myproxy-server and store credentials with it for future retrieval. Any number of these lines may
appear. For backwards compatibility, these lines can also start with allowed_clients instead of
accepted_credentials. If no accepted_credentials lines are specified, the server will not allow
any clients to store credentials.

authorized_retrievers “DN regex”
Each of these lines allows the server administrator to set server-wide policies for credential
retrievers. If the client DN does not match the given limited regex, the client is not allowed to
retrieve credentials from the server. In addition to the server-wide policy, myproxy also
provides support for per-credential policy. The user can specify the regex DN of the allowed
retrievers of the credential when uploading the credential (using myproxy-init(1) or myproxy-
store(1)). The retrieval client DN must also match the user specified regex. In order to retrieve
credentials the client also needs to know the name and pass phrase provided by the client when the
credentials were stored. Any number of these lines may appear. For backwards compatibility, these
lines can also start with allowed_services instead of authorized_retrievers. If no
authorized_retrievers lines are specified, the server will not allow any clients to retrieve
credentials.

default_retrievers “DN regex”
Each of these lines allows the server administrator to set server-wide default policies. The regex
specifies the clients who can access the credentials. The default retriever policy is enforced if
a per-credential policy is not specified on upload (using myproxy-init(1) or myproxy-store(1)).
In other words, the client can override this policy for a credential on upload. The per-
credential policy is enforced in addition to the server-wide policy specified by the
authorized_retrievers line (which clients can not override). Any number of these lines may be
present. For backwards compatibility, if no default_retrievers line is specified, the default
policy is "*", which allows any client to pass the per-credential policy check. (The client must
still pass the authorized_retrievers check.)

authorized_renewers “DN regex”
Each of these lines allows the server administrator to set server-wide policies for authorized
renewers. If the client DN does not match the given limited regex the client is not allowed to
renew the credentials previously stored by a client. See allow_self_authorization below for a
further restriction on this policy. In addition to the server-wide policy, myproxy also provides
support for per-credential policy. The user can specify the regex DN of the allowed renewers of
the credential on upload (using myproxy-init(1)). The renewal client DN must match both this
regex and the user specified regex. In this case, the client must also already have a credential
with a DN matching the DN of the credentials to be retrieved, to be used in a second authorization
step (see the -a options for myproxy-logon(1) and myproxy-retrieve(1)).

default_renewers “DN regex”
Each of these lines allows the server administrator to set server-wide default renewer policies.
The regex specifies the clients who can renew the credentials. The default renewer policy is
enforced if a per-credential policy is not specified on upload (using myproxy-init(1)). This is
enforced in addition to the server-wide policy specified by the authorized_renewers line. Any
number of these lines may appear. For backwards compatibility, if no default_renewers line is
specified, the default policy is "*", which allows any client to pass the per-credential policy
check. (The client must still pass the authorized_renewers check.)

authorized_key_retrievers “DN regex”
This policy controls who can retrieve credentials (certificates and keys) directly from the
repository using myproxy-retrieve(1). Clients must also match the authorized_retrievers policy.
If no authorized_key_retrievers lines are specified, the server will not allow any clients to
retrieve keys directly from the repository.

default_key_retrievers “DN regex”
This policy applies if a per-credential policy is not specified on upload (using myproxy-init(1)
or myproxy-store(1)). In other words, the client can override this policy for a credential on
upload. The per-credential policy is enforced in addition to the server-wide policy specified by
the authorized_key_retrievers line (which clients can not override). Any number of these lines
may be present. If no default_key_retrievers line is specified, the default policy is "*", which
allows any client to pass the per-credential policy check. (The client must still pass the
authorized_key_retrievers check.)

trusted_retrievers “DN regex”
This policy controls who can retrieve credentials without further authentication. By default,
clients that match authorized_retrievers must perform additional authentication (such as
passphrase, PAM, or SASL) to retrieve credentials. However, authenticated clients that match both
authorized_retrievers and trusted_retrievers do not need to perform additional authentication,
unless the credentials are protected by a passphrase, in which case the passphrase is still
required. Note: The myproxy-server(8) will fail on startup or reconfig with an "unsafe policy"
error if a policy of trusted_retrievers “*” is specified without also specifying a restrictive
default_trusted_retrievers policy, to avoid an unsafe policy that would release credentials to all
clients without additional authentication. See also allow_self_authorization below for a further
restriction on this policy.

default_trusted_retrievers “DN regex”
If a user doesn't set a trusted retrieval policy with the credential on upload (via 'myproxy-init
-Z'), the myproxy-server(8) will apply the following policy in addition to the trusted_retrievers
policy. If no default_trusted_retrievers policy is set, then only the trusted_retrievers policy
is applied.

The following lines in the configuration file set other server options.

passphrase_policy_program full-path-to-script
This line specifies a program to run whenever a passphrase is set or changed for implementing a
local password policy. The program is passed the new passphrase via stdin and is passed the
following arguments: username, distinguished name, credential name (if any), per-credential
retriever policy (if any), and per-credential renewal policy (if any). If the passphrase is
acceptable, the program should exit with status 0. Otherwise, it should exit with non-zero
status, causing the operation in progress (credential load, passphrase change) to fail with the
error message provided by the program's stdout. Note: You must specify the full path to the
external program. $GLOBUS_LOCATION can't be used in the myproxy-server.config file. A sample
program is installed in $GLOBUS_LOCATION/share/myproxy/myproxy-passphrase-policy but is not
enabled by default.

Be sure to follow secure coding practices for this call-out:
- Don't allow input to overflow fixed-size buffers.
- Don't pass unchecked input to a shell command.

cert_dir full-path-to-certificates-directory
Specifies the path to the CA certificates directory to be returned to clients requesting trust
roots (such as via the myproxy-logon(1) -T option).

max_proxy_lifetime hours
This line specifies a server-wide maximum lifetime for retrieved proxy credentials. By default,
no server-wide maximum is enforced. However, if this option is specified, the server will limit
the lifetime of any retrieved proxy credentials to the value given.

max_cred_lifetime hours
This line specifies a server-wide maximum lifetime for stored credentials. By default, no server-
wide maximum is enforced. However, if this option is specified, the server will limit the
lifetime of any stored credentials to the value given.

ignore_globus_limited_proxy_flag boolean
By default, MyProxy will respect the policy of "limited" proxy certificates as follows. If a
client authenticates with a limited proxy, the client should only be able to obtain another
limited proxy, not a full proxy or end entity certificate. Thus, the MyProxy CA will not accept
limited proxies for authentication. However, if this option is set to true, MyProxy will treat
limited proxy certificates as if they were full proxy certificates.

allow_self_authorization boolean
By default, MyProxy will disallow trusted_retrievers and authorized_renewers whose DN matches the
identity of the stored credential, so a proxy by itself can not be refreshed or renewed. However,
if this option is set to true, this restriction is lifted.

syslog_ident name
You can optionally specify the string to be prepended to every message written to the syslog. If
not specified, the name defaults to the the program name, i.e. myproxy-server.

syslog_facility name
By default, the myproxy-server will log to the syslog "daemon" facility. With this option you can
specify an alternate syslog facility, such as "auth", "user", "security", or "local0". The
facility can also be specified numerically as with the logger(1) command.

request_timeout seconds
Specifies the maximum time a myproxy-server(8) child process should spend servicing a client
request before aborting. By default, child processes will abort after 120 seconds. A negative
value will disable the timeout.

request_size_limit bytes
Limits the amount of incoming application-level protocol data the myproxy-server(8) will accept
from clients, to avoid memory exhaustion under heavy load. Specified in bytes. Defaults to 1MB
(1048576 bytes). A zero or negative value disables the limit.

proxy_extfile full-path-to-extension-file
Optionally specifies the full path to a file containing an OpenSSL formatted set of certificate
extensions to include in all proxy certificates issued from the MyProxy repository (analogous to
certificate_extfile for the CA module).

proxy_extapp full-path-to-extension-callout-program
This is the call-out version of proxy_extfile. It optionally specifies the full path to a call-
out program for specifying proxy certificate extensions. It will be passed the authenticated
username and the proxy credential location as the two command arguments. On success, it should
write the OpenSSL formatted set of certificate extensions to stdout and exit with zero status. On
error, it should write to stderr and exit with nonzero status. Either proxy_extfile or
proxy_extapp can be specified but not both.

Be sure to follow secure coding practices for this call-out:
- Don't allow input to overflow fixed-size buffers.
- Don't pass unchecked input to a shell command.

voms_userconf full-path-to-voms-configuration-file
Optionally specifies the full path to the VOMS configuration file containing VOMS server
information. It is usually specified in the environmental variable VOMS_USERCONF.

allow_voms_attribute_requests boolean
If this parameter is set to true and a GET request includes VONAME and (optionally) VOMSES
parameters, call-out to VOMS to add the requested attributes to the issued certificate. Requires
linking with VOMS libraries. By default, VONAME and VOMSES parameters in requests will be ignored
unless this parameter is set to true.

The MyProxy server can be optionally configured for authentication based on Pluggable Authentication
Modules (PAM) and/or the Simple Authentication and Security Layer (SASL). Kerberos is one of the
supported SASL authentication methods. The following options control the use of PAM and SASL.

pam option
This line governs the use of PAM to check passphrases. MyProxy will attempt to authenticate via
PAM, with the supplied username and passphrase. Note that PAM will need to be configured
externally for the application "myproxy" (usually in /etc/pam.d/), or for the application named by
pam_id, below. Accepted values:

required
PAM password authentication is required under all conditions. If the credential is
unencrypted (that is, it has no passphrase), a PAM password check is still required for
authentication. If the credential is encrypted, its passphrase must match the PAM
password.

sufficient
The user's passphrase may match either the credential passphrase or, if the credential is
unencrypted, the PAM passphrase. If the credential is encrypted, then the PAM password is
not relevant.

disabled (default)
PAM is not used to check passphrases.

pam_id string
The name that myproxy uses to identify itself to PAM. Default is "myproxy". For example, on most
Unix-like systems, if pam_id is set to "login", MyProxy will authenticate against the system's own
usernames and passwords.

sasl option
This line governs the use of SASL authentication. Accepted values:

required
SASL authentication is required for retrieving credentials.

sufficient
SASL authentication is sufficient for retrieving credentials, but other authentication
methods may be used instead.

disabled (default)
SASL authentication isn't used.

sasl_mech mechanism
Forces the use of a single SASL mechanism, overriding the SASL configuration file. (Typically not
required.)

sasl_serverFQDN hostname
Configures the SASL server fully-qualified domain name for multi-homed servers. (Typically not
required.)

sasl_user_realm realm
Configures the SASL user realm. (Typically not required.)

The MyProxy server can also be configured to act as a Certificate Authority (CA) to issue credentials to
clients. The following parameters enable and configure the CA functionality.

certificate_issuer_cert full-path-to-certificate
This line specifies the full path to the issuer certificate to optionally configure the myproxy-
server to act as an online certificate authority.

certificate_issuer_key full-path-to-key
When specifying certificate_issuer_cert above, you must also give the name of the CA private key
for signing certificates. This is normally path to a CA private key in PEM format, but if you are
using an OpenSSL engine (see certificate_openssl_engine_id ) then it can be the key name.

certificate_issuer_key_passphrase “passphrase”
If the certificate_issuer_key is encrypted, give the passphrase here.

certificate_issuer_subca_certfile full-path-to-subca-certificate-file
If you would like an intermediate/sub-CA certificate chain to be sent along with the EEC (End
Entity Certificate) generated using a local intermediate/sub-CA, specify the file that contains
those certificates in PEM format. This is meant to aid scenarios where the CA used is an
intermediate CA (i.e. not a root CA) and the client may not have the intermediate CA(s) in its
trust store. The client will write out the chain into the same file as the EEC, following the EEC.

certificate_issuer_hashalg algorithm
Specifies the hash algorithm to use when signing end-entity certificates. Defaults to "sha256".

certificate_issuer_email_domain “domain”
If set, specifies the domain part of the X509v3 Subject Alternative Name email address included in
issued certificates.

certificate_openssl_engine_id engineId

certificate_openssl_engine_pre pre-initialization-commands

certificate_openssl_engine_post post-initialization-commands
These commands can be used to allow any OpenSSL engine to be used with MyProxy. This enables the
use of hardware tokens and signing modules to sign certificates. Given the parameters of an
OpenSSL "engine" command, the first argument, the identity of the engine becomes the argument to
certificate_openssl_engine_id and -pre commands are listed in order using
certificate_openssl_engine_pre and -post commands are listed in order using
certificate_openssl_engine_post. For example the command-line:

openssl engine dynamic -pre SO_PATH:/usr/lib/engines/engine_pkcs11.so -pre ID:pkcs11 -pre
LIST_ADD:1 -pre LOAD -pre MODULE_PATH:/usr/lib/opensc-pksc11.so

becomes:

certificate_openssl_engine_id "dynamic"

certificate_openssl_engine_pre "SO_PATH:/usr/lib/engines/engine_pkcs11.so" "ID:pkcs11"
"LIST_ADD:1" "LOAD" "MODULE_PATH:/usr/lib/opensc-pksc11.so"

Please note that any shared library engines loaded through the "dynamic" engine MUST be compiled
againt the correct version of OpenSSL. The Globus toolkit has its own installation and can be
found by running $GLOBUS_LOCATION/bin/openssl version.

certificate_openssl_engine_lockfile full-path-to-file
If your hardware token or HSM is unable to handle simultaneous operations, provide a path to a
lockfile for synchronizing operations to the engine device. The myproxy-server will create the
file if it does not already exist.

certificate_issuer_program full-path-to-script
This line specifies the path to a program to issue certificates for authenticated clients that
don't have credentials stored. This optionally configures the myproxy-server to act as an online
certificate authority, allowing programmatic control over the certificate issuance process. You
can either specify certificate_issuer_cert or certificate_issuer_program.

Be sure to follow secure coding practices for this call-out:
- Don't allow input to overflow fixed-size buffers.
- Don't pass unchecked input to a shell command.

certificate_serialfile full-path-to-serial-file
Specifies the path to a file to store the serial number counter for issued certificates. Defaults
to /var/lib/myproxy/serial.

certificate_serial_skip increment
Specifies the number to add to the serial number each time a certificate is issued. Use this to
stagger serial numbers across multiple CA instances to avoid serial number clashes. Defaults to 1.

certificate_out_dir full-path-to-putput-directory
Specifies the path to a directory where new certificates will be archived.

max_cert_lifetime hours
Specifies the maximum lifetime (in hours) for certificates issued by the CA module. Defaults to
12 hours.

min_keylen bits
Specifies the minimum RSA key length (in bits) for certificates issued by the CA module.

certificate_extfile full-path-to-extension-file
Optionally specifies the full path to a file containing an OpenSSL formatted set of certificate
extensions to include in all issued certificates. For example:
keyUsage=digitalSignature,keyEncipherment,dataEncipherment
subjectKeyIdentifier=hash
authorityKeyIdentifier=keyid,issuer:always
crlDistributionPoints=URI:http://ca.ncsa.uiuc.edu/4a6cd8b1.r0
basicConstraints=CA:FALSE
If not set, the MyProxy CA will include a basic set of extensions in issued certificates.

certificate_extapp full-path-to-extension-callout-program
This is the call-out version of certificate_extfile. It optionally specifies the full path to a
call-out program for specifying certificate extensions. It will be passed the authenticated
username as the single command argument. On success, it should write the OpenSSL formatted set of
certificate extensions to stdout and exit with zero status. On error, it should write to stderr
and exit with nonzero status. Either certificate_extfile or certificate_extapp can be specified
but not both.

Be sure to follow secure coding practices for this call-out:
- Don't allow input to overflow fixed-size buffers.
- Don't pass unchecked input to a shell command.

certificate_mapfile full-path-to-mapfile
When specifying certificate_issuer_cert above, you can map account names to certificate subject
distinguished names for the issued certificates using this mapfile, which has the same format as
used by other Globus Toolkit services. By default, /etc/grid-security/grid-mapfile is used. The
Globus Toolkit grid-mapfile-add-entry and grid-mapfile-delete-entry commands can be used to manage
the grid-mapfile.

certificate_mapapp full-path-to-mapapp
When specifying certificate_issuer_cert above, you can map account names to certificate subject
distinguished names for the issued certificates using this call-out. It will be passed the
authenticated username as the single command argument. On success, it should write the
distinguished name in OpenSSL one line format (for example, "/C=US/O=National Computational
Science Alliance/CN=Jim Basney") to stdout and exit with zero status. On error, it should write
to stderr and exit with nonzero status. If it is not defined, then mapfile lookup will be
executed instead (see certificate_mapfile above). An example is installed in
$GLOBUS_LOCATION/share/myproxy/myproxy-certificate-mapapp.

Be sure to follow secure coding practices for this call-out:
- Don't allow input to overflow fixed-size buffers.
- Don't pass unchecked input to a shell command.

certificate_request_checker full-path-to-callout-program
This CA call-out can be used to perform checks on incoming certificate requests. It will be passed
the certificate request in PEM format on stdin. If it returns a nonzero exit status, the CA will
abort without signing the request. When returning a nonzero exit status, the callout should
indicate the problem on stderr. An example is installed in
$GLOBUS_LOCATION/share/myproxy/myproxy-certreq-checker.

certificate_issuer_checker full-path-to-callout-program
This CA call-out can be used to perform checks on issued certificates before the certificate is
returned to the client. It will be passed the certificate in PEM format on stdin. If it returns a
nonzero exit status, the CA will abort without returning the signed certificate to the client.
When returning a nonzero exit status, the callout should indicate the problem on stderr. An
example is installed in $GLOBUS_LOCATION/share/myproxy/myproxy-cert-checker.

If OpenLDAP support is built-in to the myproxy-server(8), the following parameters can be used to
configure the CA module to map account names to certificate subject distinguished names via LDAP.

ca_ldap_server “ldap://localhost:389/”
This parameter specifies the URI to the LDAP server to use for username to DN resolution in the CA
module. Both ldap:// and ldaps:// protocols are supported. A port number may optionally be
specified as well. Defining this directive is the "trigger" that causes the name resolution
module to use LDAP querying. If it is not defined, then mapfile lookup will be executed instead
(see certificate_mapfile above).

ca_ldap_uid_attribute “uid”
The name of the record attribute that maps to the MyProxy username. Required for LDAP username to
DN resolution.

ca_ldap_searchbase “ou=people,dc=bullwinkle,dc=lbl,dc=gov”
The DN of the region of the ldap database to be searched. Required for LDAP username to DN
resolution.

ca_ldap_dn_attribute “subjectDN”
If this directive is set, the LDAP resolver will pull the DN from the specified attribute in the
returned record. If it is not set, the default is to use the DN of the record itself.

ca_ldap_connect_dn “cn=MyProxy,ou=ldapusers,dc=lbl,dc=gov”
DN for LDAP basic authentication (optional).

ca_ldap_connect_passphrase “passphrase”
Passphrase for LDAP basic authentication (optional).

The following parameters control server replication with the myproxy-replicate(1) utility.

slave_servers server:port;
This value is for use with the myproxy-replicate(1) utility. This tag provides a list of servers
that will be used as secondary repositories for the MyProxy database. Each server should be
seperated by a ";". Also, a port may be provided if the slave server is using a port other then
the default. The server name maybe a recognized DNS or an IP address.

The following parameters are used primarily when utilizing MyProxy as a delegation service for web
portals.

accepted_credentials_mapfile full-path-to-mapfile
This parameter points to a grid-mapfile, which is possibly different from other mapfiles above.
When specified, this mapfile is utilized during puts/stores (e.g. with myproxy-init(1) and
myproxy-store(1)). A credential is authorized to be put/stored only under the username specified
in the mapfile. This prevents storing a user's credential under a different username. Note that
the credential checked for the presence of a SubjectDN/Username entry in the mapfile is the
credential utilized to secure the connection between client and server, NOT the actual credential
being stored. As the credential which secures the TLS connection is typically the same as the
credential being stored, this should not be a major issue. The Globus Toolkit grid-mapfile-add-
entry and grid-mapfile-delete-entry commands can be used to manage the grid-mapfile.

accepted_credentials_mapapp full-path-to-mapapp
As an alternative to the accepted_credentials_mapfile option above, you can specify a call-out
which is passed two parameters: a certificate subject distinguished name and a username (in that
order). In essence, the call-out performs a lookup in a 'virtual' accepted_credentials_mapfile.
If the SubjectDN/Username line would appear in such a mapfile, then the call-out should exit with
zero status indicating that a credential with the given SubjectDN is allowed to be stored under
the given Username. Otherwise, the call-out should exit with nonzero status indicating error. An
example is installed in $GLOBUS_LOCATION/share/myproxy/myproxy-accepted-credentials-mapapp.

Be sure to follow secure coding practices for this call-out:
- Don't allow input to overflow fixed-size buffers.
- Don't pass unchecked input to a shell command.

check_multiple_credentials boolean
Typically when a credential is accessed by a client, the server checks only one credential for
possible access authorization, even if there are multiple credentials stored under the given
username. If this option is set to "true" AND the client does not specify a credential name for a
MyProxy GET operation (i.e., from myproxy-logon(1)), then the server will check multiple
credentials with the given username. If a credential is found to be authorized for client access,
then that one will be used during processing. The default value for this option is "false".

The following parameters enable OCSP status checking of stored credentials in the myproxy-server(8)
repository, to avoid use of expired credentials.

ocsp_policy policy
Controls the policy for checking certificate validity via OCSP before credentials may be
delegated. Currently, only the status of the end entity certificate is checked via OCSP (and not
any proxy certificates or CA certificates). OCSP will not be used unless ocsp_responder_url
and/or ocsp_policy are set. Supported policies are:
"aia" - use OCSP responder in certificate AIA extension, if
present; otherwise use ocsp_responder_url, if set

ocsp_responder_url URL
Specifies the URL of an OCSP responder to use to check the validity of credentials stored in the
myproxy-server repository before they may be delegated, so that revoked credentials can not be
retrieved and used where their revocation status may not be checked. Currently, only the status
of the end entity certificate is checked via OCSP (and not any proxy certificates or CA
certificates). In any case, CRL checks are always performed. Both http and https urls are
supported. OCSP will not be used unless ocsp_responder_url and/or ocsp_policy are set.

ocsp_responder_cert path
Specifies the path to the certificate of a trusted OCSP responder. This is needed if the OCSP
responder must be explicity trusted in cases where standard path validation fails for the OCSP
responder's certificate.

The following parameters control Usage Metrics reporting by the myproxy-server(8).

disable_usage_stats value
By default Usage Metrics reporting is enabled. Specifying "true", "enabled", "yes", "on" or "1"
for value will disable Usage Metrics reporting. Setting the GLOBUS_USAGE_OPTOUT environment
variable to "1" will also disable the reporting of usage metrics. Disabling reporting of usage
metrics will cause the usage_stats_target setting to be ignored.

usage_stats_target target_list
This option can be used to specify the target collector hosts to which usage metrics should be
reported. This setting will be ignored if disable_usage_stats is enabled. Multiple targets can be
specified in target_list separated by comma(s). Each target specification is of the format
host:port[!tags]. The tags control what data elements are reported. The following list specifies
the tags for the corresponding data elements.
V - Major Version number of MyProxy server
v - Minor Version number of MyProxy server
t - Task Code (0=Get, 1=Put, 2=Info, 3=Destroy, 4=ChangeCredPassphrase, 5=StoreEndEntCred,
6=RetrEndEntCred, 7=GetTrustRoots)
r - Task Return Code.
l - Requested Lifetime for Credential.
L - Actual Lifetime for Credential.
B - Informational Bit mask to be interpreted left to right as follows:
PAM used
SASL used
Credential passphrase check used
Trusted Retriever (Certificate-based authentication)
Certificate Authorization method used (Trusted Renewer)
Pubcookie was used
Trustroots requested
Trustroots delivered
I - Client IP address
u - Username
U - User DN

In addition to the above selected information, the following data are reported to ALL the
specified/default target collectors. There's no way to exclude these from being reported other
than by disabling the reporting of usage metrics:

Component code - 11 for MyProxy
Component Data Format version - 0 currently
IP Address of Reporting Server
Timestamp
Hostname

If no tags are specified in a host spec, or the special string "default" is specified, the tags
VvtrlLB are assumed. A site could choose to allow a different set of data to be reported by
specifying a different tag set. The last 3 tags I, u and U above are more meant for a local
collector that a site might like to deploy since they could be construed as private information.
The special string "all" denotes all tags.

By default, Usage Metrics reporting is disabled. This can be made explicit by specifying
"default" (all by itself) for the target specification as in:

usage_stats_target "default"

REGULAR EXPRESSIONS

       For matching distinguished names (DNs) in access control policies, MyProxy uses  POSIX  Extended  Regular
       Expressions  (see  re_format(7)),  with custom processing of '*', '?', and '.' metacharacters to simulate
       Unix shell  style  wildcard  processing  (for  backward  compatibility  and  other  historical  reasons).
       MyProxy's custom regular expressions are converted to POSIX EREs according to the following rules:

         [ MyProxy regex ] => [ POSIX ERE ]
         ----------------------------------
                '*'        =>      '.*'
                '?'        =>      '.'
                '.'        =>      '\.'
                '\*'       =>      '*'
                '\?'       =>      '?'
                '\.'       =>      '.'

       Additionally, MyProxy wraps all regular expressions inside '^(' and ')$' to require full DN matching.

       Be  aware  that  parentheses  are  metacharacters according to POSIX, so escaping is required for literal
       matching. For example:

         "*/CN=Jim Basney \(admin\)"

       The following examples illustrate how MyProxy regular expressions are converted to POSIX EREs:

            [ MyProxy regex ]     =>    [ POSIX ERE ]
         ------------------------------------------------------------
         "*/CN=Jim Basney"        => "^(.*/CN=Jim Basney)$"

EXAMPLES

       The following policy enables all credential repository features.

       accepted_credentials       "*"
       authorized_retrievers      "*"
       default_retrievers         "*"
       authorized_renewers        "*"
       default_renewers           "none"
       authorized_key_retrievers  "*"
       default_key_retrievers     "none"
       trusted_retrievers         "*"
       default_trusted_retrievers "none"
       cert_dir                   /etc/grid-security/certificates

       The following enables CA functionality using an existing Globus Simple CA configuration.

       authorized_retrievers "*"
       pam  "sufficient"
       sasl "sufficient"
       certificate_issuer_cert /home/globus/.globus/simpleCA/cacert.pem
       certificate_issuer_key /home/globus/.globus/simpleCA/private/cakey.pem
       certificate_issuer_key_passphrase "myproxy"
       certificate_serialfile /home/globus/.globus/simpleCA/serial
       certificate_mapfile /etc/grid-security/grid-mapfile
       cert_dir /etc/grid-security/certificates

       The following will cause usage metrics to be reported to the default target (only the  default  tags)  as
       well as a local collector (including the tags IuU):

       usage_stats_target "usage-stats.cilogon.org:4810,localcollector.somedomain:4810!VvtrlLBIuU"
