Dear Team,

In our setup we are having 6 MIC cards on 3 host machines.

Out of 6 mic cards, 1 card is not working with ldap authentication.

The troubleshooting steps given below:-

[root@phi1-mic0 ~]# rpm -qa | grep ldap
[root@phi1-mic0 ~]#
[root@phi1-mic0 ~]# logout
Connection to phi1-mic0 closed.
[root@nandadevi1 ~]# ssh phi1-mic1
[root@phi1-mic1 ~]# rpm -qa | grep ldap
libldap-2.4-2-2.4.23-r1.k1om
nss-ldap-265-r0.k1om
pam-ldap-186-r0.k1om
[root@phi1-mic1 ~]#
