HELP Domain authentication suddenly not working

[lokiset]

I can't log on to my Ubuntu server with any domain accounts anymore, it was working perfectly for several weeks and now nothing. I'm not sure where to start looking the error when I try to ssh in just say access denied.

can somebody point me in the right direction please? what logs should I be looking in or other trouble shooting steps to take?

thanks

Please describe your setup and then paste the relevant configuration files like your /etc/ssh/sshd_config.

my setup is taken from here sshd config wouldn't that effect only ssh? I can't log on locally with domain accounts anymore either, it was working just fine for about a month.

Mostly, the problem is that the clock is wrong. The client and server need to be within 5 minutes of each other for Kerberos to work.

thanks for your reply, I checked and the time was only off by about 1 minute, I synced it up with the server and still no go.
