Issue Summary

When a group is deleted in the external directory, the syncing process deletes the user group itself from groups in Confluence. However, if there are any assigned permissions for this group, the definition remains in the Global Permission and Space Permission page.

Steps to Reproduce

1. Integrate with OpenLDAP/Microsoft Active Directory
2. Create a test group in the external user directory
3. Sync the user directory and check the test group is created in Confluence 
4. Assign some permissions in the Global/Space Permission page
5. Delete the test group
6.  Check the Global/Space Permission page

Expected Results

The permissions are deleted for the test group

Actual Results

The permissions remain for the test group with Group not found mark.

Workaround

1. Delete these records in Web UI
2. Delete from database
   1. On the database, run the following query to get the records for deleted group:

      SELECT * 
      FROM spacepermissions 
      WHERE permgroupname not in (Select group_name from cwd_group); 

   2. and delete these records after verification:

      DELETE
      FROM spacepermissions 
      WHERE permgroupname not in (Select group_name from cwd_group);
