I'v updated ZCM 10.2.2 to 10.3 Update 3 (Beta).
I cannot log anymore to ZCM with users that are in my LDAP server. Error is :

Login Error: com.novell.zenworks.datamodel.exceptions.InternalD ataModelException: org.hibernate.exception.SQLGrammarException: could not load an entity: [com.novell.zenworks.datamodel.objects.authsources. ldap.LDAPAuthoritativeSource#fb8767a2026886fd706fb a491929f3ac]
See the ZENworks Control Center log file (zcc.log) for the full stack trace.

I've forgotten the Administraor password (it is just a test server :-) ) so I cannot log anymore.

Any idea?
