Kerberos & SSH & OD / AD

I've been looking around for an answer to this problem I've been having for a bit now (sorry if this is the wrong subforum). I am having an issue with kerberizing SSH login. Our systems are bound to OD and AD. I can login to the systems with either OD or AD users at the login prompt but I can only login thru SSH via OD users. So to recap because everyone loves a bulleted list: * Working: login window with AD and OD * Working: ssh with OD user * Not working: ssh with AD user I would assume if the login window worked that SSH would work thru the same mechanism as well but I guess not. Do I need to enable GSSAPIAuthentication on the client and server or should it work "magically" like the login window works? I've tried just about everything I can think of so I would love to hear if anyone is able to successfully login thru SSH via AD. I am probably missing something rather simple here. Thanks in advance.
