ADFS 3.0 and UPN Problem
Posted on 2016-11-22
I will do my best to describe our setup.
Windows 2012 R2 ADFS Proxy in the DMZ and one Windows 2012 R2 ADFS internal server. Our default UPN for all users is @child.domain.com (which is the name of our internal domain holding all user accounts) we are piloting o365 right now and about 50 users had to have their UPN's updated to @domain.com. When these users try to access a host site that is setup on our ADFS server they are not able to authenticate. This worked perfectly up until their UPN was changed.
Question: how can I setup ADFS to have select user get authenticated using a different UPN than our default one.
