NAME

     cvtsudoers — convert between sudoers file formats

SYNOPSIS

     cvtsudoers [-ehMpV] [-b dn] [-c conf_file] [-d deftypes] [-f output_format]
                [-i input_format] [-I increment] [-m filter] [-o output_file] [-O start_point]
                [-P padding] [-s sections] [input_file]

DESCRIPTION

     cvtsudoers can be used to convert between sudoers security policy file formats.  The default
     input format is sudoers.  The default output format is LDIF.  It is only possible to convert
     a sudoers file that is syntactically correct.

     If no input_file is specified, or if it is ‘-’, the policy is read from the standard input.
     By default, the result is written to the standard output.

     The options are as follows:

     -b dn, --base=dn
                 The base DN (distinguished name) that will be used when performing LDAP queries.
                 Typically this is of the form ou=SUDOers,dc=my-domain,dc=com for the domain
                 my-domain.com.  If this option is not specified, the value of the SUDOERS_BASE
                 environment variable will be used instead.  Only necessary when converting to
                 LDIF format.

     -c conf_file, --config=conf_file
                 Specify the path to the configuration file.  Defaults to /etc/cvtsudoers.conf.

     -d deftypes, --defaults=deftypes
                 Only convert Defaults entries of the specified types.  One or more Defaults
                 types may be specified, separated by a comma (‘,’).  The supported types are:

                 all       All Defaults entries.

                 global    Global Defaults entries that are applied regardless of user, runas,
                           host or command.

                 user      Per-user Defaults entries.

                 runas     Per-runas user Defaults entries.

                 host      Per-host Defaults entries.

                 command   Per-command Defaults entries.

                 See the Defaults section in sudoers(5) for more information.

                 If the -d option is not specified, all Defaults entries will be converted.

     -e, --expand-aliases
                 Expand aliases in input_file.  Aliases are preserved by default when the output
                 format is JSON or sudoers.

     -f output_format, --output-format=output_format
                 Specify the output format (case-insensitive).  The following formats are
                 supported:

                 JSON      JSON (JavaScript Object Notation) files are usually easier for third-
                           party applications to consume than the traditional sudoers format.
                           The various values have explicit types which removes much of the
                           ambiguity of the sudoers format.

                 LDIF      LDIF (LDAP Data Interchange Format) files can be imported into an LDAP
                           server for use with sudoers.ldap(5).

                           Conversion to LDIF has the following limitations:

                           ·  Command, host, runas and user-specific Defaults lines cannot be
                              translated as they don't have an equivalent in the sudoers LDAP
                              schema.

                           ·  Command, host, runas and user aliases are not supported by the
                              sudoers LDAP schema so they are expanded during the conversion.

                 sudoers   Traditional sudoers format.  A new sudoers file will be reconstructed
                           from the parsed input file.  Comments are not preserved and data from
                           any include files will be output inline.

     -h, --help  Display a short help message to the standard output and exit.

     -i input_format, --input-format=input_format
                 Specify the input format.  The following formats are supported:

                 LDIF      LDIF (LDAP Data Interchange Format) files can be exported from an LDAP
                           server to convert security policies used by sudoers.ldap(5).  If a
                           base DN (distinguished name) is specified, only sudoRole objects that
                           match the base DN will be processed.  Not all sudoOptions specified in
                           a sudoRole can be translated from LDIF to sudoers format.

                 sudoers   Traditional sudoers format.  This is the default input format.

     -I increment, --increment=increment
                 When generating LDIF output, increment each sudoOrder attribute by the specified
                 number.  Defaults to an increment of 1.

     -m filter, --match=filter
                 Only output rules that match the specified filter.  A filter expression is made
                 up of one or more key = value pairs, separated by a comma (‘,’).  The key may be
                 “user”, “group” or “host”.  For example, user = operator or host = www.  An
                 upper-case User_Alias or Host_Alias may be specified as the “user” or “host”.

                 A matching sudoers rule may also include users, groups and hosts that are not
                 part of the filter.  This can happen when a rule includes multiple users, groups
                 or hosts.  To prune out any non-matching user, group or host from the rules, the
                 -p option may be used.

                 By default, the password and group databases are not consulted when matching
                 against the filter so the users and groups do not need to be present on the
                 local system (see the -M option).  Only aliases that are referenced by the
                 filtered policy rules will be displayed.

     -M, --match-local
                 When the -m option is also specified, use password and group database
                 information when matching users and groups in the filter.  Only users and groups
                 in the filter that exist on the local system will match, and a user's groups
                 will automatically be added to the filter.  If the -M is not specified, users
                 and groups in the filter do not need to exist on the local system, but all
                 groups used for matching must be explicitly listed in the filter.

     -o output_file, --output=output_file
                 Write the converted output to output_file.  If no output_file is specified, or
                 if it is ‘-’, the converted sudoers policy will be written to the standard
                 output.

     -O start_point, --order-start=start_point
                 When generating LDIF output, use the number specified by start_point in the
                 sudoOrder attribute of the first sudoRole object.  Subsequent sudoRole object
                 use a sudoOrder value generated by adding an increment, see the -I option for
                 details.  Defaults to a starting point of 1.  A starting point of 0 will disable
                 the generation of sudoOrder attributes in the resulting LDIF file.

     -p, --prune-matches
                 When the -m option is also specified, cvtsudoers will prune out non-matching
                 users, groups and hosts from matching entries.

     -P padding, --padding=padding
                 When generating LDIF output, construct the initial sudoOrder value by
                 concatenating order_start and increment, padding the increment with zeros until
                 it consists of padding digits.  For example, if order_start is 1027, padding is
                 3, and increment is 1, the value of sudoOrder for the first entry will be
                 1027000, followed by 1027001, 1027002, etc.  If the number of sudoRole entries
                 is larger than the padding would allow, cvtsudoers will exit with an error.  By
                 default, no padding is performed.

     -s sections, --suppress=sections
                 Suppress the output of specific sections of the security policy.  One or more
                 section names may be specified, separated by a comma (‘,’).  The supported
                 section name are: defaults, aliases and privileges (which may be shortened to
                 privs).

     -V, --version
                 Print the cvtsudoers and sudoers grammar versions and exit.

     Options in the form “keyword = value” may also be specified in a configuration file,
     /etc/cvtsudoers.conf by default.  The following keywords are recognized:

     defaults = deftypes
           See the description of the -d command line option.

     expand_aliases = yes | no
           See the description of the -e command line option.

     input_format = ldif | sudoers
           See the description of the -i command line option.

     match = filter
           See the description of the -m command line option.

     order_increment = increment
           See the description of the -I command line option.

     order_start = start_point
           See the description of the -O command line option.

     output_format = json | ldif | sudoers
           See the description of the -f command line option.

     padding = padding
           See the description of the -P command line option.

     prune_matches = yes | no
           See the description of the -p command line option.

     sudoers_base = dn
           See the description of the -b command line option.

     suppress = sections
           See the description of the -s command line option.

     Options on the command line will override values from the configuration file.

FILES

     /etc/cvtsudoers.conf      default configuration for cvtsudoers

EXAMPLES

     Convert /etc/sudoers to LDIF (LDAP Data Interchange Format) where the ldap.conf file uses a
     sudoers_base of my-domain,dc=com, storing the result in sudoers.ldif:

           $ cvtsudoers -b ou=SUDOers,dc=my-domain,dc=com -o sudoers.ldif \
                        /etc/sudoers

     Convert /etc/sudoers to JSON format, storing the result in sudoers.json:

           $ cvtsudoers -f json -o sudoers.json /etc/sudoers

     Parse /etc/sudoers and display only rules that match user ambrose on host hastur:

           $ cvtsudoers -f sudoers -m user=ambrose,host=hastur /etc/sudoers

     Same as above, but expand aliases and prune out any non-matching users and hosts from the
     expanded entries.

           $ cvtsudoers -ep -f sudoers -m user=ambrose,host=hastur /etc/sudoers

     Convert sudoers.ldif from LDIF to traditional sudoers format:

           $ cvtsudoers -i ldif -f sudoers -o sudoers.new sudoers.ldif
