Environment

Novell Filr 2.0

Situation

On some Filr systems LDAP sync task fails when there is sufficient idle time (in some tests 25 minutes) between the last time Filr contacted the LDAP server. This can happen if processing of users/groups takes long enough before the next set of users/groups is requested from the LDAP server.

The following error stack sequence is observed in appserver.log file when this happens:

2016-02-02 16:24:30,746 ERROR [http-apr-8443-exec-12] [org.kablink.teaming.module.ldap.impl.LdapModuleImpl] - An error was encountered syncing groups.  Ldap sync will not continue.

Resolution

A fix for this issue is available in the Filr 2.0 Hot Patch 1, available via the Novell Patch Finder.
