I modified the file: /var/yp/Makefile. Here is the content:

I modified the option of "MERGE_PASSWD" from "true" to "false".
I added the user name "dstest". And run the command "passwd dstest" and execute the "make" command.

When I run the command "ypcat passwd" on the nis client as root, it displayed

Code:

dstest:x:500:500::/home/dstest:/bin/bash

But when I run the command " su - dstest" on the nis client, after log into, I execute the "ypcat passwd" command, it displayed

Code:

No such map passwd.byname. Reason: No such map in server's domain

Here is the content when I execute the "ypwhich -x" as dstest:

Code:

Use "ethers"    for map "ethers.byname"

Use "aliases"  for map "mail.aliases"

Use "services"  for map "services.byname"

Use "protocols" for map "protocols.bynumber"

Use "hosts"    for map "hosts.byname"

Use "networks"  for map "networks.byaddr"

Use "group"    for map "group.byname"

Use "passwd"    for map "passwd.byname"

Here is the content of nis client's file: /etc/yp.conf

Code:

domain nistest server hostname.domainname.com # sorry, I can't tell you what the real name is

Here is the content of nis client's file: /etc/nsswitch.conf

Code:

passwd:    files nis

shadow:    files nis

group:      files nis

hosts:      files nis dns

bootparams: nisplus [NOTFOUND=return] files



ethers:    files

netmasks:  files

protocols:  files nisplus nis

rpc:        files

services:  files nisplus nis

netgroup:  files nisplus nis

publickey:  nis

automount:  files nisplus nis

aliases:    files nisplus

Here is the content of nis server's file:/etc/ypserv.conf

Code:

dns: no

files: 30

slp: no

slp_timeout: 3600

xfr_check_port: yes

*                          : *      : passwd.byname    : port

*                          : *      : shadow.byname    : port

*                          : *      : passwd.adjunct.byname : port

Here is the content of nis server's file: /etc/pam.d/login

Code:

auth      required    pam_securetty.so

auth      required    pam_stack.so service=system-auth

auth      required    pam_nologin.so

account    required    pam_stack.so service=system-auth

password  required    pam_stack.so service=system-auth

session    required    pam_stack.so service=system-auth

session    required    pam_loginuid.so

session    optional    pam_console.so



session    required    pam_selinux.so open

Here is the content of nis server's file: /etc/pam.d/system-auth

Code:

password    required      /lib/security/$ISA/pam_deny.so



session    required      /lib/security/$ISA/pam_limits.so

session    required      /lib/security/$ISA/pam_unix.so

Also, here is the problem after I use " su - dstest" and execute the command "id dstest":

Code:

id: dstest: No such user

Why the root user can execute "ypcat passwd", but dstest can't.
By the way, the all machines are in the same Lan.

Please help me. Thank you very much!
