Problem: Automounting Home directory for nis & nfs configuration doesn't work
Hi all,
First of all, i am so sorry about my bad level in English writing.
I have some problem in linux and i hope the experts of this forum to help me if they have enough time to reply to me.

I have a scenario of configuring NIS and NFS in Redhat Linux environment such that user can login from any machine in the network and after he login, the home directory is supoosed to be mounted from the server using the automounting .
I configured the NFS server and NIS server and i checked everything and it is supposed everything is OK (all the related daemons are running). But the problem started when i start configuring the client. I started by configuring the NFS client because my goal is to mount the home directory of the user from the server once he login to the client machine. After i configured the NFS, i configured the NIS client. as i could see, NIS works well, because i can get the passwd file from the NIS server by running the command 'ypcat passwd' in the NIS client. But the problem started when i tried to log in in the client machine. The error which appeared showed that i can't login because the home directory is not found. If i login as root, no error appear and i can login. But when i try to login using the other accounts which created in the NIS server, i can't login because that error appears.

I followed the next procedure to configure the two machines:server and client:
1- in the server:
- i add "/home *(rw,sync)" to the file /etc/exports
- i run the command exportfs -a
- i run and chkconfug: nfslock, nfs and portmap

2- in the client:
- i run and chkconfig: nfslock, netfs, and portmap
- i duplicate the home directory, rename the new copy to home.old and delete all the contents of the original home
- i mounted the home of the server to the home directory in the client using the mount command and it worked. then i unmount it using umount.
- i added "/home /etc/auto.home --timeout 600" to etc/auto.master file
- i created the file etc/auto.home and i add this line to it "* -fstype=nfs,soft,intr,rsize=8192,wsize=8192,nosuid,tcp /
<server ip address>:/home:&"
- i run and chkconfig autofs

3- in the server:
- i edit /etc/sysconfig/network by adding the line "NISDOMAIN="NIS-SCHOOL-NETWORK""
- i edit /etc/yp.conf by adding the line "ypserver 127.0.0.1"
- i run and chkconfig: portmat, yppasswdd, ypserv
- i run /usr/lib/yp/ypinit -m
- i run and chkconfig ypbind and ypxfrd
- i added a new user in the server and set his password

4- in the client
- i run authconfig and specify the name of domain and the server ip address
- i run and chkconfig portmap, ypbind
- i verifed the name resolution of both client and server
- i tested nis access to nis server by runing ypcat in the client to get passwd file
- i can ssh from the server to the client by using one of the account created in the nis server.

after this step: when i tried to login from the client using one of the nis server accounts, the next error appears: home directory not found and i can't login. when i login using the root account i can login.


So, pleeeeeeeeeeeeeeeeeeeeeeeeeeeeeas help me in this problem
Thanks in advance

ypinit

ypinit(1M)						  System Administration Commands						ypinit(1M)

NAME

       ypinit - set up NIS client

SYNOPSIS

       /usr/sbin/ypinit [-c] [-m] [-s master_server]

DESCRIPTION

       ypinit  can be used to set up an  NIS client system.  You must be the superuser to run this command. This script need not be used at all if
       ypbind(1M) is started with the -broadcast option (it is invoked with this option from the svc:/network/nis/client:default service).

       Normally,  ypinit is run only once after installing the system. It may be run whenever a new NIS server is  added  to  the  network  or	an
       existing one is decommissioned.

       ypinit  prompts	for a list of NIS servers to bind the client to; this list should be ordered from the closest to the furthest server. Each
       of these NIS servers must be listed in either the /etc/hosts or the /etc/inet/ipnodes file along with its IP  address.  ypinit  stores  the
       list in file /var/yp/binding/domain/ypservers. This file is used by ypbind when run without the	-broadcast option.

OPTIONS

       -c		       Set up a ypclient system.

       -m		       Build a master ypserver data base.

       -s master_server        Slave  data  base.  master_server  must be the same master configured in the YP maps and returned by the ypwhich -m
			       command.

FILES

       /etc/hosts

       /etc/inet/ipnodes

       /var/yp/binding/domain/ypservers

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       +-----------------------------+-----------------------------+
       |Availability		     |SUNWnisu			   |
       +-----------------------------+-----------------------------+

SEE ALSO

       svcs(1), svcadm(1M), ypbind(1M), sysinfo(2), hosts(4), ipnodes(4), attributes(5), smf(5)

NOTES

       The NIS client service is managed by the service management facility, smf(5), under the service identifier:

       svc:/network/nis/client:default

       Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed  using  svcadm(1M).  The  ser-
       vice's status can be queried using the svcs(1) command.

BUGS

       ypinit  sets  up  the  list  of	NIS  servers only for the current domain on the system when it is run, that is, the domain returned by the
       SI_SRPC_DOMAIN command to sysinfo(2). Care should be taken to ensure that this is the same as the desired domain for NIS client processes.
