I encountered a couple of strange events with respect to password authentication this morning. Two of our staff were unable to login onto several systems using their usual passwords. Both users had last logged in on these hosts using their accounts and passwords on Friday past.

Resetting both the passwords to their current values using the passwd utility on each system corrected the problem insofar as the users were concerned. However, I am somewhat perplexed as to the reason for their passwords to stop working in the first place. Is anyone here aware of any reason why this might happen?
Is it possible that they'd logged into something else first, and had multiple credentials, and the systems were trying to get those first?
