Allowing the Use of an E-Mail Address as the Logon User Name
Topic Last Modified: 2005-05-24
An additional option for authentication is to configure a user principal name (UPN) for users. This enables users to enter their e-mail address as their user name. You must configure all virtual servers and all virtual directories on each front-end and back-end server which will be accessed with UPN authentication. After you configure a UPN in the properties of the virtual servers and directories on all front-end and back-end servers, users can authenticate by using email@example.com as their user name. Additionally, users can still use the domain\username logon.
