Connect via ssh using active directory authentication

view story

http://www.unix.com – I want to connect via SSH that will authenticate via active directory (domain controller). For example my network login in my workstation is user123/123user under a domain. I wanted to use this details to login via ssh. In this way I don't have to add and create username everytime in the server (ie. linux, solaris, redhat) I believe this can be done by configuring kerberos and external PAM? Pls advise if anyone in here knows the procedure. thank you for assistance (HowTos)
