We have recently upgrading to ZCM 10.3.1.0
Operating System: Novell SuSE Linux Enterprise Server 10
Source set to eDirectory.
I can access the users in our user source through ZCC.
But new created users cannot login to Zenworks anymore:

Unable to log into the ZENworks realm because the system had disconnected
from the network and the specified credentials did not match with the
credentials cached on system.
Actual Results:
Unable to log into the ZENworks realm because the system had disconnected from
the network and the specified credentials did not match with the credentials
cached on system.

On the ZEN server we have this notice:
Query failed.:
com.novell.zenworks.datamodel.exceptions.ObjectNot FoundException:
