My Windows 2008 R2 machine is joined to a domain.

In the logon screen, if I type in "[email protected]:something" as the username, I can still logon properly, what's the meaning of ":something" appended at the end?

I can even see the current user is displayed as "[email protected]:something" in the switch user screen. Is it a feature in Windows? Or is it just a bug? If it is a feature, what's the difference between logging in as "[email protected]" and logging in as "[email protected]:something"?

Note that I tried different combinations like "mydomain\username:something" and "mydomain.com:something\username". None of them work except "[email protected]:something".
