SUMMARY
Windows 2000 offers the new possibility of a "single logon" for users. Therefore, a user's logon name and e-mail address can be the same in Windows 2000. For example, John@microsoft.com can be an e-mail address and a logon name in a Windows 2000 domain. John can still choose to log on by using domain\john, or just john if he chooses.
A user's name in the form of user@domain.com is known as the User Principal Name (UPN). This option only works in a Windows 2000 domain environment (in other words, you must have Active Directory running, and the user must be in a domain account in that directory).
When you are using Basic Authentication, a small amount of setup is required for this feature to function properly. This also assumes that the e-mail address, domain, and user name are intentionally made to be identical (although later versions of Exchange Server should make this much easier to work with).
MORE INFORMATION
To configure your Web site to accept UPNs when you are using Basic authentication, perform the following steps:
- Open the Internet Services Manager (or custom management console that contains the IIS snap-in).
- Expand your Web sites, and then click to highlight the Web site where you want to enable the UPN logon.
- Right-click the Web site, and then click Properties.
- Click the Directory Security tab.
- Under the Anonymous Access and Authentication Control section, click Edit.
- Next to Basic Authentication, click Edit. (Note that this step assumes that you already are using Basic Authentication. If you are not using it, click to enable the Basic Authentication check box and make sure to disable other forms of authentication).
- Under the Domain Name section, insert \.
- Click OK, and then exit the Web site property sheet. (Make sure to click OK on the other windows to ensure that your changes take effect.)
To test your configuration, log on to a Web site by using Basic authentication, use user@domain.com (provided your domain is 'domain.com') and than enter your password as usual.
NOTE: You can still log on to multiple domains in this way by using user@domain.com, or the standard domain\user, or domain.com\user.
