Hi Uday,
It would give more light on your problem if you could share some error details, logs or more details on your scenario.
From what I understand from your message, you have a log-on methodology for OData services defined to use Alternate Logon Procedure, there would be additional steps involved to enable this.
Like, your SAP system should be in trust with AD, which I consider the bare minimum for authentication.
Br,
