	I read the thread, u hv actually posted most of the info.
	 
	U r missing binddn and bindpw in /etc/ldap.conf at the ldap client
	 
	1) Add a proxyagent person, i.e. import the followings into LDAP tree data
	 
	dn: ou=profile,dc=example,dc=com
	ou: profile
	objectClass: top
	objectClass: organizationalUnit
	dn: cn=proxyagent,ou=profile,dc=example,dc=com
	cn: proxyagent
	sn: proxyagent
	objectClass: top
	objectClass: person
	userPassword: {CRYPT}l14aeXtphVSUg
	 
	2) Add ACL in slapd.conf to allow proxyagent to read user info. (change the specfic pls), and restart ldap service
	 

	access to attr=userPassword

	            by self write

	            by * auth

	access to dn="ou=People,dc=example,dc=com"

	            by self write

	            by dn="cn=proxyagent,ou=profile,dc=example,dc=com" read

	            by users auth

	            by anonymous read

	access to * by self write

	            by * read

	 
	# service ldap restart
	 
	3) edit /etc/ldap.conf at ldap client, add these lines on top of what u already have, protect this file as mode 400
	 
	binddn cn=proxyagent,ou=profile,dc=platts,dc=mhm,dc=mhc
	bindpw password
	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
	# Filter to AND with uid=%s
	#pam_filter objectclass=account
	pam_filter objectclass=posixAccount
	# The user ID attribute (defaults to uid)
	pam_login_attribute uid
	

	Good luck to u.

		1) Hv u checked dir perms for /etc and /etc/openldap?
		ls -ld /etc; ls -ld /etc/openldap
		 
		2) I assume u hv run authconfig, if so, edit /etc/pam.d/system-auth
		change this:

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

		to that:

		

		account     sufficient      /lib/security/$ISA/pam_unix.so
		 
		3) if 1) and 2) do not help
		 
		Can u post these files on ldap client (full content pls) to us (or to just me as too much info):
		/etc/ldap.conf,
		/etc/openldap/ldap.conf
		/etc/pam.d/system-auth
		/etc/nsswitch.conf
		/etc/resolv.conf
		/etc/hosts
		 
		and these files on ldap server:
		slapd.conf
		 
		output of:
		partial ldapsearch output showing the testuser user details
		rpm -qa | grep openldap
		rpm -qa | grep nss_ldap
		rpm -qa | grep pam
		strace id testuser (u must hv strace rpm installed)
		ldd `which id`
		 
		Rgds
