Problems with ldap and owncloud synchronization

Hello.
problems with synchronization. partially does not work.
new users created in the univention directory are created in owncloud.
but.
users deleted from the univention user directory are not removed from owncloud. also when changing the name in univention in owncloud the old name does not change.

debug.log:
mdb_equality_candidates (owncloudenabled) not indexed
