Here is the situation I am in. I'm at work with a GNU/Linux laptop, and I would like to athenticate with our domain controllers in the hopes off accessing network resources like shares, the internet, etc ... I don't have administrive access to our servers here at work, and I would just like to authenticate and use the machine as it is without adding it to the network. Any ideas?

I've searched the internet and found something about kerberos and samba but I can't make the right end of the stick here. Help!

Thanks in advance.
