Here we go...
1. nis server for authentication
2. nfs server for each user's home dir
Let me put it this way, nisuser1 logon to nisclient*, using the nis server for authentication, if authenticated, the nisclient* will auto mount the nisuser1's home dir from the nfs server. When nisuser1 logout, his home dir will be unmounted automatically. (where nisclient* means any of nisclient machines)
I think I already got the nis part, but for the nfs part, don't know how.
Any suggestion will be really appreciated.
BTW, the nis and nfs servers are both ubuntu 8.10, nisclients are mixed, most of them are FC and RH.
Thank you in advance, I really really need help~~~~~
