CVTSUDOERS(1) BSD General Commands Manual CVTSUDOERS(1)
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 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.
/etc/cvtsudoers.conf 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 \
/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
