Rolegroups
A rolegroup is used for fine-grained delegation. Access control rules
(ACIs) grant permission to perform given tasks (add a user, modify a group,
etc.), to task groups. Rolegroups are members of taskgroups, giving them
permission to perform the task.
The logic behind ACIs and rolegroups proceeds as follows:
ACIs grants permission to taskgroup
rolegroups are members of taskgroups
users, groups, hosts and hostgroups are members of rolegroups
Rolegroups can contain both hosts and hostgroups, enabling
operations using the host service principal associated with a machine.
Rolegroups can not contain other rolegroups.
EXAMPLES:
Add a new rolegroup:
ipa rolegroup-add --desc="Junior-level admin" junioradmin
Add this role to some tasks:
ipa taskgroup-add-member --rolegroups=junioradmin addusers
ipa taskgroup-add-member --rolegroups=junioradmin change_password
ipa taskgroup-add-member --rolegroups=junioradmin add_user_to_default_group
Yes, this can seem backwards. The taskgroup is the entry that is granted
permissions by the ACIs. By adding a rolegroup as a member of a taskgroup
it inherits those permissions.
Add a group of users to this role:
ipa group-add --desc="User admins" useradmins
ipa rolegroup-add-member --groups=useradmins junioradmin
Display information about a rolegroup:
ipa rolegroup-show junioradmin
