Are you using pam_ldap.conf & nslcd.conf for RHEL6 authentication
against LDAP server, RHEL6 dont use legacy ldap.conf file.

Make sure you /etc/pam_ldap.conf look something like this.

base dc=example,dc=com
binddn cn=manager
bindpw XXXX
scope sub
nss_base_passwd          ou=People,dc=example,dc=com?one
nss_base_shadow          ou=People,dc=example,dc=com?one
nss_base_group          ou=Group,dc=example,dc=com?one
uri ldaps://ldapserver.example.com/
pam_groupdn cn=servers-mgmt,ou=servers,dc=example,dc=com
pam_member_attribute member
ssl no
tls_cacertdir /etc/openldap/cacerts
pam_password crypt

btw why NSLCD ? Why not SSSD, Read below for more information on SSSD.

Hi
Thanks for that,
I just configured by using sssd.
its working fine
but still , it does not restrict user ..i was following this

http://www.couyon.net/1/post/2012/04/enabling-ldap-usergroup-support-and-aut...

and my configuration is

[sssd]
config_file_version = 2
services = nss, pam
 domains = LDAP
[nss]
filter_users = root,ldap,named,avahi,haldaemon,dbus,radiusd,news,nscd
[pam]
# Example LDAP domain
 [domain/LDAP]
 id_provider = ldap
 auth_provider = ldap
 ldap_schema = rfc2307bis
 ldap_uri = ldap://auth4.uk.xxxx.lan
 ldap_search_base = l=uk,dc=xxxx,dc=lan
 ldap_group_member = uniquemember
ldap_access_filter = cn=system-users,ou=Groups,l=uk,dc=xxxxx,dc=lan
 chpass_provider = ldap
tls_reqcert = demand
ldap_tls_cacert = /etc/openldap/cacerts/CA-lego.crt

and i used the according :
http://docs.fedoraproject.org/en-US/Fedora/15/html/Deployment_Guide/chap-SSS...

#%PAM-1.0
# This file is auto-generated.
# User changes will be destroyed the next time authconfig is run.
