Hi Tom,

NIS+ stands for Network Information Service Plus. It was designed to
replace NIS, and is a default naming service for Solaris. NIS+ can
provide limited support to NIS clients via a YP-compatibility mode.
NIS+ was mainly designed to address problems that NIS cannot address.

One important thing to note is that there is no relation between NIS+
and NIS. The commands and the overall structure of NIS+ are different
from NIS. In addition, some command syntax in NIS+ is different from
the NIS commands. NIS+ was designed from scratch.

By default, NIS+ ships with support for common Unix flat files. Here is the list of default databases which NIS+ supports; notice how most of them are also popular Unix flat files.

aliases auto_home auto_master bootparams ethers
group hosts netgroup netid netmasks
networks passwd protocols publickey rpc
services shadow timezone

See info here...

What files will NIS replicate accross servers from the NIS server to the clients. Will it replicate the /etc/hosts, /etc/passwd/, user directories such as /home/user?

Thanks

It doesn't actually replicate files to the clients. The clients have processes running that talk to the NIS+ server to get the information that it needs.

You can use NIS+ for passwd file entries, group file entries, hosts file info (I think). You can use automounter to mount home directories from a central server, but NIS+ itself does not mount the directory, it just provides the path that you need.
