Removed duplicities in ad services
Created by: balcirakpeter
- Methods add_members_to_entry, remove_members_from_entry and update_groupMembership were moved to the ADConnector.pm to prevent duplicities in ad_mu and ad_group_mu_ucn scripts.
- These methods had to be slightly changed as they cannot update counters. Instead of that they return result codes, which are used in the destination scripts to update appropriate counters.
