Hello  Nalin and all

I just added "ssl  on"  to below /etc/ldap.conf file and get below error msg in var/log/secure file :-


sshd[6212]: pam_unix(sshd:session): session closed for user test1
sshd[6248]: pam_unix(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=192.168.1.1  user=test1
sshd[6248]: Accepted password for test1 from 192.168.1.1 port 47171 ssh2
sshd[6248]: pam_unix(sshd:session): session opened for user test1 by (uid=0)
sshd[6248]: pam_unix(sshd:session): session closed for user test1

sshd[6284]: pam_ldap: ldap_simple_bind Can't contact LDAP server
sshd[6284]: Failed password for test1 from 192.168.1.1 port 47172 ssh2

With "ssl on" in ldap.conf, am unable to login via ssh

any helpers please... 

regards
Dharmin
