Groups of users
Manage groups of users. By default new groups are not Posix groups.
You can mark it as Posix at creation time with the --posix flag and
can promose a non-Posix group using the --posix flag in group-mod.
Once a group is a Posix group there is no way to undo this.
Every group must have a description.
Posix groups must have a group id number (gid). Changing a gid is
supported but can have impact on your file permissions.
EXAMPLES:
Add a new group:
ipa group-add --desc='local administrators' localadmins
Add a new posix group:
ipa group-add --posix --desc='remote administrators' remoteadmins
Promote a non-posix group to posix:
ipa group-mod --posix localadmins
Create a group with a specific group ID number"
ipa group-add --posix --gid=500 --desc='unix admins' unixadmins
Remove a group:
ipa group-del unixadmins
Manage group membership, nested groups:
ipa group-add-member --groups=remoteadmins localadmins
Manage group membership, users:
ipa group-add-member --users=test1,test2 localadmins
Manage group membership, users:
ipa group-remove-member --users=test2 localadmins
Show a group:
ipa group-show localadmins
