My AD domain is domain.com and all of my users have a UPN of firstname.lastname@example.org, which matches their email address. Everyone can login to self service using the UPN without any issue., we instruct them to use their "email address" as the uesrname.
I have a group of users in my domain that I do not host their email. They actually are part of an entirely separate AD domain and there is no trusts to that domain, nor can there be. But, thees users need logins in my domain for some of our resources, and to show up in our GAL. We have created "mail userr" objects for them in AD/Exchange. This is different than a regular AD user in that they have an AD account but the email address is an external address (like a contact) These users have a UPN of email@example.com and an email address defined of firstname.lastname@example.org
I'd like to allow these users to login to self-service using their email address (email@example.com). To try and make this worked I added "Email" and "Email Proxy Address" as additional properties in self-service admin, properties for users section.
When I then try to login to self servce using firstname.lastname@example.org, I receive a red message saying "'otherdomain.com' is not operational"
Is there any way to make this work?
