Comment 16 for bug 354378

cdmdotnet,

It sounds like you're describing the same basic issue here. You may be able to get more useful information out of the error if you run strace with '-s 128', so that you can see the full message - that won't get you to a fix for this bug, but you might find out what extra information PAM is trying to give you, and address that if it points to another problem.
