We have allot of resource on Windows side. The linux group are using NIS. They want to get rid of NIS. They want a single sign on to access the resources on Linux side and Windows Side. They want to athenthicate against our AD for linux and windows. The only way I know is thru the NIS. I just have to make some changes in the schema. But they don't want to use NIS. The only was I can think of is to make their user id work kerbores.
