Subject: [PATCH] SDAP: Add sdap_handle_id_collision_for_incomplete_groups()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This newly added function is a helper to properly hadle group
id-collisions when renaming incomplete groups and it does:
- Deletes the group from sysdb
- Adds the new incomplete group
- Notifies the NSS responder that the entry also has to be deleted from
the memory cache
This function will be called from
sdap_ad_save_group_membership_with_idmapping() and from
sdap_add_incomplete_groups().
