IE authentication prompt

hi, a bit random but at a complete loss. We've had microsoft identity manager installed and that has a web front end that users can administer their user account. However, when the user navigates to the internal servers url, they are prompted for a user name and password, which is fine, but the only way they can log on is if they enter \username and password. Normally, i'd expect either domain\username or simply username, but for the life of me, i can't work out why it needs the \ to authenticate.

In chrome it just works with the username and password, but in Edge and IE, its the whole \ thing. Ironically, on the server itself, in IE you can also log in with username/password without having to worry about the .

Any pointers would be appreciated.

    Hi,

    Thanks! The issue you've found actually solved my problem.

    After a certain period of idleness, my Edge will ask me to complete Browser SSO before I can continue to use it. But no matter I use Domain\username + Password or Username + Password, I failed to sign on. I have to close my Edge and open it again to sign on.

    I tried \username + Password and it succeeded!

    I think the \ tells system that it should go to a domain to find the username. And in an AD domain environment, system will go directly to the domain and search for an object whose name is username. If we use Domain\username, system will go to domain domain to find the object named username. And domain domain doesn't exist. If we use username without the \, system will consider this account as a local account instead of a domain account. The verification will fail too.

    It's only my personal view. If I find official documentation for this behavior, I will post the link here. I'd appreciated any correction of my misunderstanding.
