My users currently have to log on to Outlook Web Access (OWA) with domain\username. I want to let them log on with only a username. Can I eliminate the domain and use just a username and password for logon?

—Chris Shaver

Yes. Whether you run OWA 2000 or OWA 5.5, Microsoft IIS authenticates the user's credentials. You must tell IIS to assume a default domain instead of requiring that the user provide a domain name. (For instructions about how to configure the new logon process, see the Microsoft article "How to Authenticate a User Against All Trusted Domains" at http://support.microsoft.com/default.aspx?scid=kb;en-us;q168908.) Of course, if you use OWA 2000, users can also log on with their user principal names (UPNs)—such as paul@robichaux.local—which resolves the domain problem neatly.

I have tried this fix with no success. Can this also be done in a front end environment when using SSL? I am under the impression that only basic authentication can be used for front end configurations.
