Currently users are having trouble knowing which user/pwd combo they have to use to log in. Maybe displaying information on the log in page along the lines of 'Sign in with your AD user (for Windows users this is the same you use to log in to your computer, for other users, use your login name (not e-mail!) and Outlook password)'
Some UX input is necessary to make this idea suitable.
