Infrastructure Software

HI,
I am having a solaris nis server and a file server running on solaris (pre installed).I need to add new workstations (linux) to this server, i stopped firewall and selinux on linux pc & configured network.I used authconfig to configure nis client. In the NIS server cd /var/yp/src and edited netgroup & hosts.
and then used make command. Now If i give su <nisusername> it allows authentication but without home directory.
Plz tell me which file i need to edit in NIS inorder to get the homedirectory of logged user.
(might be the hostname of the linux system to be given in any file in NIS server)
Thank you All
