Thanks for the reply. Answers to your question:
>> Whats the SEPM version you are running?
v12.1.5 (RU5)
>> Multipie domains?
Yes
>> when you used AD test for connectivity, was it successful?
Yes, it was a successful test for AD. But when I try to login, it fails. Error log does not state why. Just 'Incorrect ID & password' even that I know the ID/password is correct.
If I get nowhere with this, I will raise a call.
Cheers
