NIS and Samba

Today I spent a lot of time playing with NIS and Samba. I am trying to finalize my connectivity between Fedora and W2K3. I have Unix Services installed on the Windows Server and it offers NIS. After playing with it and learning a lot more about it, I have decided not to use it. The key is Samba and Kerberos. If I get Samba and Kerberos correctly configured, then NIS would be redundant. The best resource I have found is but I do not have it working yet. The login and mount is not working even though I have joined the computer to the domain and modified the login pam. I am still researching the problem(s).
