DESCRIPTION

       Slapd  is  the stand-alone LDAP daemon. It listens for LDAP connections
       on any number of ports (default 389), responding to the LDAP operations
       it receives over these connections.  slapd is typically invoked at boot
       time, usually out of /etc/rc.local.  Upon startup, slapd normally forks
       and  disassociates  itself from the invoking tty.  If configured in the
       config file (or config directory), the slapd  process  will  print  its
       process  ID (see getpid(2)) to a .pid file, as well as the command line
       options during invocation to an .args file (see slapd.conf(5)).  If the
       -d  flag  is  given, even with a zero argument, slapd will not fork and
       disassociate from the invoking tty.

       See the "OpenLDAP Administrator's Guide" for more details on slapd.

OPTIONS

       -4     Listen on IPv4 addresses only.

       -6     Listen on IPv6 addresses only.

       -T tool
              Run in Tool mode. The tool argument selects whether  to  run  as
              slapadd,  slapcat, slapdn, slapindex, slappasswd, slapschema, or
              slaptest (slapacl and slapauth need  the  entire  acl  and  auth
              option  value  to  be spelled out, as a is reserved to slapadd).
              This option should be the first  option  specified  when  it  is
              used;   any   remaining  options  will  be  interpreted  by  the
              corresponding slap tool program, according to the respective man
              pages.   Note  that these tool programs will usually be symbolic
              links to slapd.  This option is provided  for  situations  where
              symbolic links are not provided or not usable.

       -d debug-level
              Turn  on debugging as defined by debug-level.  If this option is
              specified, even with a zero argument, slapd  will  not  fork  or
              disassociate from the invoking terminal.  Some general operation
              and status messages are printed for any  value  of  debug-level.
              debug-level   is   taken   as   a  bit  string,  with  each  bit
              corresponding to a  different  kind  of  debugging  information.
              Comma-separated  arrays  of  friendly  names can be specified to
              select  debugging  output   of   the   corresponding   debugging
              information.  All the names recognized by the loglevel directive
              described in slapd.conf(5) are supported.  If debug-level is  ?,
              a list of installed debug-levels is printed, and slapd exits.

              Remember  that if you turn on packet logging, packets containing
              bind passwords will be output, so if you redirect the log  to  a
              logfile, that file should be read-protected.

       -s syslog-level
              This option tells slapd at what debug-level debugging statements
              should be logged to the syslog(8) facility.  The  value  syslog-
              level  can  be set to any value or combination allowed by the -d
              switch.  Slapd logs all messages selected  by  syslog-leveli  at
              the  syslog(3) severity debug-level DEBUG, on the unit specified
              with -l.

       -n service-name
              Specifies the service  name  for  logging  and  other  purposes.
              Defaults to basename of argv[0], i.e.: "slapd".

       -l syslog-local-user
              Selects  the  local user of the syslog(8) facility. Value can be
              LOCAL0, through LOCAL7, as well as USER and DAEMON.  The default
              is  LOCAL4.   However,  this option is only permitted on systems
              that support local users with the syslog(8)  facility.   Logging
              to syslog(8) occurs at the "DEBUG" severity debug-level.

       -f slapd-config-file
              Specifies   the   slapd   configuration  file.  The  default  is
              /etc/ldap/slapd.conf.

       -F slapd-config-directory
              Specifies the slapd  configuration  directory.  The  default  is
              /etc/ldap/slapd.d.   If both -f and -F are specified, the config
              file will be read and converted to config directory  format  and
              written  to  the  specified  directory.   If  neither  option is
              specified,  slapd  will  attempt  to  read  the  default  config
              directory  before  trying  to  use the default config file. If a
              valid config directory exists then the default  config  file  is
              ignored.  All  of  the  slap  tools  that use the config options
              observe this same behavior.

       -h URLlist
              slapd will by default serve  ldap:///  (LDAP  over  TCP  on  all
              interfaces  on  default LDAP port).  That is, it will bind using
              INADDR_ANY and port 389.  The -h option may be used  to  specify
              LDAP (and other scheme) URLs to serve.  For example, if slapd is
              given -h "ldap://127.0.0.1:9009/ ldaps:/// ldapi:///",  it  will
              listen  on  127.0.0.1:9009  for  LDAP, 0.0.0.0:636 for LDAP over
              TLS, and LDAP over IPC  (Unix  domain  sockets).   Host  0.0.0.0
              represents  INADDR_ANY  (any interface).  A space separated list
              of URLs is expected.  The URLs should be of the LDAP, LDAPS,  or
              LDAPI  schemes,  and  generally  without  a DN or other optional
              parameters (excepting as  discussed  below).   Support  for  the
              latter  two  schemes  depends on selected configuration options.
              Hosts may be specified by name or IPv4 and IPv6 address formats.
              Ports,  if specified, must be numeric.  The default ldap:// port
              is 389 and the default ldaps:// port is 636.

              The listener permissions are  indicated  by  "x-mod=-rwxrwxrwx",
              "x-mod=0777"  or  "x-mod=777", where any of the "rwx" can be "-"
              to suppress the related permission, while any of the "7" can  be
              any legal octal digit, according to chmod(1).  The listeners can
              take  advantage  of  the  "x-mod"  extension  to   apply   rough
              limitations  to  operations,  e.g.  allow  read operations ("r",
              which applies to search and  compare),  write  operations  ("w",
              which  applies  to  add, delete, modify and modrdn), and execute
              operations  ("x",  which  means  bind  is   required).    "User"
              permissions apply to authenticated users, while "other" apply to
              anonymous users; "group" permissions are ignored.  For  example,
              "ldap:///????x-mod=-rw-------" means that read and write is only
              allowed for authenticated connections, and bind is required  for
              all  operations.   This feature is experimental, and requires to
              be manually enabled at configure time.

       -r directory
              Specifies a directory to become the root directory.  slapd  will
              change  the current working directory to this directory and then
              chroot(2)  to  this  directory.   This  is  done  after  opening
              listeners   but   before   reading  any  configuration  file  or
              initializing any backend.  When used as a security mechanism, it
              should be used in conjunction with -u and -g options.

       -u user
              slapd  will  run  slapd  with the specified user name or id, and
              that  user's  supplementary  group  access  list  as  set   with
              initgroups(3).  The group ID is also changed to this user's gid,
              unless the -g option is used to override.  Note when  used  with
              -r,  slapd  will  use  the  user  database  in  the  change root
              environment.

              Note that on some systems, running as a non-privileged user will
              prevent passwd back-ends from accessing the encrypted passwords.
              Note also that any shell back-ends will  run  as  the  specified
              non-privileged user.

       -g group
              slapd  will  run with the specified group name or id.  Note when
              used with -r, slapd will use the group database  in  the  change
              root environment.

       -c cookie
              This  option  provides  a  cookie  for  the syncrepl replication
              consumer.  The cookie is a comma separated  list  of  name=value
              pairs.  Currently supported syncrepl cookie fields are rid, sid,
              and  csn.   rid  identifies  a  replication  thread  within  the
              consumer  server  and is used to find the syncrepl specification
              in  slapd.conf(5)  or  slapd-config(5)   having   the   matching
              replication  identifier  in  its  definition.  The  rid  must be
              provided in order for any other specified  values  to  be  used.
              sid   is   the   server   id   in   a   multi-master/mirror-mode
              configuration.  csn is the commit sequence number received by  a
              previous   synchronization  and  represents  the  state  of  the
              consumer  replica  content  which  the  syncrepl   engine   will
              synchronize to the current provider content.  In case of mirror-
              mode or multi-master replication agreement, multiple csn values,
              semicolon separated, can appear.  Use only the rid part to force
              a full reload.

       -o option[=value]
              This option provides a generic means to specify options  without
              the need to reserve a separate letter for them.

              It supports the following options:

              slp={on|off|slp-attrs}
                     When  SLP  support  is  compiled  into  slapd, disable it
                     (off),
                      enable it by registering at SLP DAs without specific SLP
                     attributes  (on),  or  with  specific SLP attributes slp-
                     attrs that must  be  an  SLP  attribute  list  definition
                     according to the SLP standard.

                     For        example,       "slp=(tree=production),(server-
                     type=OpenLDAP),(server-version=2.4.15)" registers at  SLP
                     DAs  with  the three SLP attributes tree, server-type and
                     server-version that have the values  given  above.   This
                     allows to specifically query the SLP DAs for LDAP servers
                     holding the production tree in case  multiple  trees  are
                     available.

EXAMPLES

       To  start slapd and have it fork and detach from the terminal and start
       serving the LDAP databases defined in the  default  config  file,  just
       type:

            /usr/sbin/slapd

       To  start  slapd  with  an  alternate  configuration  file, and turn on
       voluminous debugging which will be printed on standard error, type:

            /usr/sbin/slapd -f /var/tmp/slapd.conf -d 255

       To test whether the configuration file is correct or not, type:

            /usr/sbin/slapd -Tt
