How to NIS Server in RHEL 4 AS

Very Happy Hello to All,
I am preparing for RHCE Exam.I have got a couple of problems while configuring NIS Server
in RHEL 4 AS .I followed the below listed steps to configure and the main problem is in NIS Client machines users home directory is not mounted showing mounting user in '/' .
rpms
ypserv
ypbind
yp-tools
I edited vi /etc/sysconfig/network and added NISDOMAIN="www.pjk.com"
#vi /etc/yp.conf
ypserver 127.0.0.1
Started the following daemons: portmap, yppasswdd, and ypserv.
created nis database:
cd /usr/lib/yp/
[root@www yp]#./ypinit -m
services ypbind and ypxfrd started
service ypbind restart
service ypxfrd restart
created a user #useradd nisuser
#passwd nisuser
---
cd /var/yp
#make
done.
now in client machine i run authconfig and selected nis,given domainname=www.pjk.com
server ip=192.168.1.2
restarted ypbind
now,in client i tried to login as user 'nisuser'
and getting error 'not found /home/nisuser',while /home/nisuser is present in nis server.and i
can login in server as 'nisuser'!.I already tried to change permissions ,using /rhome/nisuser
as default homedir for nisuser etc and not working.But I had successfully configured nis server in RHEL 3 using above steps.Is this to do something with selinux>?Please geeks out there help me Idea Very Happy

For NIS to work properly, you also need to NFS mount users home directories from server. Basically all the homes will be located on a central server and mounted to clients via NFS. like this:
/etc/exports

Code:

/home      192.168.0.0/255.255.255.0(rw)

This will enable all the computer in your LAN (192.168.0.0/24) to be able to mount homes directory in read-write mode.

And in the /etc/fstab file of all the clients add the mount option.
/etc/fstab

Code:

 192.168.0.100:/home /home  nfs  rw,user 0 0

Assuming 192.168.0.100 is your NIS logon server.

Reading NFS howto from TLDP will solve this problem.

ALAS!SOLVED!Many thanks for insights of Vimal
i tried nfs in server exporting /home dir
#

code:

vi /etc/exports
/home *(rw,sync,no_root_squash)

service nfs restart
In client machine run authconfig
then configure autofs

code:

vi /etc/auto.master
/home /etc/auto.home --timeout=60
vi /etc/auto.home
* --fstype=nfs4 192.168.1.2:/home/&

service autofs restart
tried login as user nisuser in client and...
$pwd
/home/nisuser
------------------------------
If i configure client ip with dhcp,the /etc/yp.conf file gets modified everytime starting client system.what2dowhat2dowhat2dowhat2dowhat2do Please................help
That also solved by editing /etc/dhcpd.conf and adding correct
option-nis-domain value and restarted services; )

subnet 192.168.1.0 netmask 255.255.255.0 {

# --- default gateway
option routers 192.168.1.1;
option subnet-mask 255.255.255.0;

option nis-domain "www.pjk.com";
option domain-name "www.pjk.com";
option domain-name-servers 192.168.1.2;

option time-offset -18000; # Eastern Standard Time
# option ntp-servers 192.168.1.1;
# option netbios-name-servers 192.168.1.1;
# --- Selects point-to-point node (default is hybrid). Don't change this unless
# -- you understand Netbios very well
# option netbios-node-type 2;

range dynamic-bootp 192.168.1.2 192.168.1.4;
default-lease-time 21600;
max-lease-time 43200;

adding entries in /etc/fstab is worth.but i thought automount should
be also be tried as it will mount the automounted directres only
when we need them.

Automounter daemon is a better idea prakash, as exposing users home directories via NFS is a grave security risk. But then this method is useful if you plan to take an routine/incremental backup of users home directories on another computer.
