hi all,

I have setup NIS to enable used to login to NIS servers. I so some article saying NIS is not secure. Can I use it with Kerberos to authenticate user or Kerberos is used separately (as server and client)?

thanks

NIS is not considered very secure and it is incompatible with a lot of other products.
Here's an old document about NIS security: http://www.eng.auburn.edu/~doug/nis.html

NIS is being less used these days.  It's a throwback to older UNIX systems.
NIS was supposed to be replaced with NIS+, but that was never very popular because it was such a pain to set up and maintain, so both versions are still supported.

Rather than using NIS, LDAP with Kerberos is growing in popularity, and LDAP does have some Microsoft Windows Server support:
http://technet.microsoft.com/en-us/library/cc750824.aspx

Here is a doc on replacing NIS with LDAP and Kerberos.
http://www.ofb.net/~jheiss/krbldap/howto.html

If you want to continue with NIS, it would probably be worth looking at the O'Reilly NIS book:
http://docstore.mik.ua/orelly/networking_2ndEd/nfs/index.htm
In chapter 12 that talks about using Kerberos V5 for NFS mounts.

Luckily for me I've only got a few Linux users so I don't need anything so complicated!  :-)

I don't think it has to be LDAP - it's just newer and more secure.
I assume the Kerberos client is for accessing NFS disks?
