The new model is based on permssions, privileges and roles. Most importantly it corrects the reverse membership that caused problems in the previous implementation. You add permission to privileges and privileges to roles, not the other way around (even though it works that way behind the scenes). A permission object is a combination of a simple group and an aci. The linkage between the aci and the permission is the description of the permission. This shows as the name/description of the aci. ldap:///self and groups granting groups (v1-style) are not supported by this model (it will be provided separately). This makes the aci plugin internal only. ticket 445

Groups of users
|
|
|
|
Manage groups of users. By default, new groups are POSIX groups. You
|
|
can add the --nonposix to the group-add command to mark a new group
|
|
as non-POSIX, and you can use the same argument to the group-mod command
|
|
to convert a non-POSIX group to 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 number (GID). Changing a GID is
|
|
supported but can have 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
