communicator cannot connect to the server because the required security is not in place (Solved)

OCS client is  not able to expand users in any of the AD group lists . It is showing error as below
“Communicator cannot connect to the server because the required security is not in place”

Solution:
The issue was with the certificate which is not providing a secure channel between the user computer and the server

I tries the below links from the user system and found it was showing a certificate error


Note: where ocspool.yourdomain.com is the FQDN of the OCS pool

Then I installed the certificate from the IE itself and the issue resolved
