     I  don't have any Linux members but it isn't uncommon to see this 
log for windows devices. A case where I would expect to see this if the 
machine was off for 30+ days and then turned on. If memory serves me 
this is negotiated every 30 days via the default domain policy.

Anything in the syslog files of your member computers? I would look 
around the time stamp of the authentication request. Is it when it's 
powered on?
