In the past when I would create accounts in the SEP Management Console, I would use the person's Directory Authentication, and then press the button "Test Account", and it would be a success.
Now, I am trying to create an account for a new user to SEPM, and I get error, "Unable to authenticate the directory account. Verify that the directory server and account name entered are correct, and try again."
I then tested the pre-existing accounts that are already in SEPM, and that can successfully authenticate using directory authentication, and I get the same error, "Unable to authenticate the directory account. Verify that the directory server and account name entered are correct, and try again."
Why is this happening, and how do I fix it. We recently upgraded to SEP 12 RU2.
