Root Cause: ARA users were deactivated by LDAPSYNC even if they were not configured within the LDAPSYNC scope. When removing an LDAP user connected to an ARA user and running LDAPSync afterwards, all ARA users with the same name and user group, assigned to different departments and whose AE accounts were configured to connect to LDAP were deactivated and removed from the user group.
