LDAP synchronization fails

We have upgraded from confluence 3.5 with LDAP authentication and local groups.

Now when we try to synchronize with the directory it fails with the following stack trace in catalina.log.

This widget could not be displayed.

The LDAP directory has grown - the limit was the LDAP search size limit. Fixed by increasing the bind DN's search size limit.
