Define an "alternate" login domain for Active Directory

  • 772

A buddy asked me this question - and I quite honestly don't know enough about Active Directory and how to operate/configure AD to answer this.

A customer of my buddy has an AD domain DomainA and that's what's they use to sign on to Active Directory now - users sign in with their user name in the form of DomainA\John Doe.

For whatever reasons (don't ask me for those reasons!), they know what to logon with a different domain name (which is not a subdomain of the first domain) - let's say OtherDomain. So the idea is: the Active Directory still runs on DomainA, but the users log in using OtherDomain\John Doe.

Any chance this is even possible? If so: how do you set this up / configure such a scenario?

Thanks for any hints!

    This is possible. It's called a UPN and can be whatever you want.

    In Active Directory Domains and Trusts you can define a new UPN for your forest. It then becomes select-able on the Account tab of a user account in ADUC. So if your domain is Domain1 and you define domain2.whatever as a UPN suffix for a user, that user can log in as [email protected]
