Error while trying to setup LDAP Authentication

Hi
We have Centrasite 8.2 Active SOA. I am trying to set up LDAP authentication for this.
I am working with the LDAP admins. We have entered the LDAP settings in the System Management Hub (please see attached word document for the settings).

Then I tried to validate the LDAP Setting. I get the following error:
Check for group resolution failed: Can’t get groups for user. SSX LDAP Error: The supplied credential is invalid (-134)

Please let me know how I can fix this.
I appreciate your help.

Sathish.
