My helpdesk is getting a few calls today about users not being able to login to GWise. Upon checking the log files, the only thing that jumps out at me is "Error: [0051] User:<> (<>)" I've checked Google and Knowledgebase, but that error code doesn't come up. Anybody have an idea what that error code is? And/or a link to some documentation that explains it?

This is running GW 8.0.2 (12/11/2010) on SLES 10 SP2. All of our POs are configured to use LDAP Authentication only, without SSL.
