     cvtsudoers -- convert between sudoers file formats


     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]


     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 syntacti-
     cally 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

     The options are as follows:

     -b dn, --base=dn
                 The base DN (distinguished name) that will be used when per-
                 forming LDAP queries.  Typically this is of the form
                 ou=SUDOers,dc=my-domain,dc=com for the domain
                 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

     -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 ambi-
                           guity of the sudoers format.

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

                           Conversion to LDIF has the following limitations:

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

                           o  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 sup-

                 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, sepa-
                 rated 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 con-
                 sulted 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 auto-
                 matically be added to the filter.  If the -M is not speci-
                 fied, 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

     -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 pol-
                 icy.  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 con-
     figuration file, /opt/local/etc/cvtsudoers.conf by default.  The follow-
     ing 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.

           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


                               default configuration for cvtsudoers


     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 \

     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

           $ 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.ldif
