Symptom
After configuring the Active Directory Directory Access plug-in, an alert message appears at the client computer that says "invalid user name and password combination."
Solution
This happens when an incorrect name and/or password is entered, including a username entered with incorrect syntax.
The user's login name (also known as "PrincipalName") is required when binding a computer to Active Directory.
The user can also use the short part of the login name (such as "virginia"). The typical syntax of a login name is similar to "virginia@domain.forest.company.com".
Note: If the user's login name has been modified from the default "virginia@domain.forest.company.com", then the default login name must be used. The modified login name (such as "virginia@email.company.com") cannot be used.
