Groups of users

Manage groups of users. By default, new groups are POSIX groups. You
can add the --nonposix option to the group-add command to mark a new group
as non-POSIX. You can use the --posix argument with the group-mod command
to convert a non-POSIX group into a POSIX group. POSIX groups cannot be
converted to non-POSIX groups.

Every group must have a description.

POSIX groups must have a Group ID (GID) number. Changing a GID is
supported but can have an impact on your file permissions. It is not necessary
to supply a GID when creating a group. IPA will generate one automatically
if it is not provided.

EXAMPLES:

 Add a new group:
   ipa group-add --desc='local administrators' localadmins

 Add a new non-POSIX group:
   ipa group-add --nonposix --desc='remote administrators' remoteadmins

 Convert a non-POSIX group to posix:
   ipa group-mod --posix remoteadmins

 Add a new POSIX group with a specific Group ID number:
   ipa group-add --gid=500 --desc='unix admins' unixadmins

 Add a new POSIX group and let IPA assign a Group ID number:
   ipa group-add --desc='printer admins' printeradmins

 Remove a group:
   ipa group-del unixadmins

 To add the "remoteadmins" group to the "localadmins" group:
   ipa group-add-member --groups=remoteadmins localadmins

 Add a list of users to the "localadmins" group:
   ipa group-add-member --users=test1,test2 localadmins

 Remove a user from the "localadmins" group:
   ipa group-remove-member --users=test2 localadmins

 Display information about a named group.
   ipa group-show localadmins

External group membership is designed to allow users from trusted domains
to be mapped to local POSIX groups in order to actually use IPA resources.
External members should be added to groups that specifically created as
external and non-POSIX. Such group later should be included into one of POSIX
groups.

An external group member is currently a Security Identifier (SID) as defined by
the trusted domain. When adding external group members, it is possible to
specify them in either SID, or DOM\name, or name@domain format. IPA will attempt
to resolve passed name to SID with the use of Global Catalog of the trusted domain.

Example:

1. Create group for the trusted domain admins' mapping and their local POSIX group:

   ipa group-add --desc='<ad.domain> admins external map' ad_admins_external --external
   ipa group-add --desc='<ad.domain> admins' ad_admins

2. Add security identifier of Domain Admins of the <ad.domain> to the ad_admins_external
   group:

   ipa group-add-member ad_admins_external --external 'AD\Domain Admins'

3. Allow members of ad_admins_external group to be associated with ad_admins POSIX group:

   ipa group-add-member ad_admins --groups ad_admins_external

4. List members of external members of ad_admins_external group to see their SIDs:

   ipa group-show ad_admins_external
""")
