Issue in connecting to Active Directory

Hi,

Using One Identity Manager v8.2
I am trying to establish a connection with AD. The process works fine till testing domain controller connection. But, fails while loading schema.

To be specific I am getting below error in crash report.
Method:"LoadSchemaByContext" Number:"2226137" Message:"Error accessing schema: Directory server "name of DC" does not exist or cannot be contacted."

Domain admin permissions are already provided for the account that we are using to connect AD.

Below is the crash report:

Object reference not set to an instance of an object.
