FAILURE: 608 Pam not configured for VAS

Hi,

We managed to integrate RHEL5's SAMBA with Q|VAS on a server, "all" was good, however, last Thursday (Dec 3, 2009) there have been errors logged in /var/log/messages, please see the errors below. Has anyone seen this problem?

Thanks for your help/comments.
