  yes, su ldap_6 works.

From server machine [root@server]$ssh root@n20 [root@n20]$su ldap_6 it doesn't ask password and switches to ldap_6 [ldap_6@n20]$

Yes, it doesn't ask with root access, test it with a non root account...Then you should see a password prompt, and check the authentification syslog! You should see some PAM entries....

 On client node
   $getent passwd    shows
       ldap_6:x:514:514:ldap_6:/home/ldap_6:/bin/bash

      $getent shadow   shows
      ldap_6:*:13998::99999:7:::

 That means password is not getting propagated. So, how to sync 

up the password?

Thats correct, you don't have to sync the passwords! The password is only stored in the ldap tree. I guess with NSS everything is fine, you should check your pam log entries!

>Test it with a normal user, so you have to enter a password for
the ldap account


 I have set password for user ldap_6 with ldappasswd command and 

userPassword attribute shows the hash of it when I do ldapsearch for ldap_6.

Why the password for ldap_6 is not getting propagated to client 

nodes? Because of which I am unable to do $ssh ldap_6@<client-node-name> from server node.

    >Pam LDAP libraries installed and configured?

  nss_ldap and pam_ldap installed.

    >ldapsearch bind works?

   ldapsearch works on client nodes.

        Hi,

         I am using openLDAP-2.4.19-4 on fedora 12 machine. I
        have done all server and client configurations. The
        directory containing user information is getting
        available on client nodes(checked by $getent passwd) but
        I am unable to do

         $ssh <user-name>@client-node-name

        it shows
                  Permission denied
        (publickey,gssapi-keyex,gssapi-with-mic,password).

        My client node .ssh/config file contents are as follows:

        ForwardX11 yes
        StrictHostKeyChecking no
        FallBackToRsh no
        BatchMode yes
        ConnectionAttempts 5

        Compression no
        Cipher blowfish
        UserKnownHostsFile /dev/null
        CheckHostIP no


        Even I am unable to login on the client node from
        console(i.e. from client node login window itself), it
        shows authentication failure message.

        On client node with $getent passwd, it shows

         ldap_6:x:514:514:ldap_6:/home/ldap_6:/bin/bash

        but $cat /etc/shadow doesn't show any password
        information for user ldap_6. So, how do I know that
        userPassword attribute information is getting propagated
        to client nodes?
