After upgrading to 8.0.2. from 7, one of our customer gets occasional error messages that LDAP authentication has been turned off. This happens in Webaccess as well as on the Client.

LDAP lookup on the server running GroupWise agents (Linux) works fine at that moment.
After about 10 minutes the error is gone, but it reappears every once in a while (random).

Where to look for possible solutions, or error messages?
