Using UPN as the username for AD authentication

Hi all;

I’m wanting to change the username used for login from the default sAMAccountName to users UPN from AD. I’ve changed the Username attribute and User Search Filter in the Advanced section of my AD user source to reference userPrincipalName, but when I hit Manage Users nobody shows up (as they would if I use the defaults) and test logins from the associated Identify Provider start to fail. I’m doing something wrong…just not sure what…


By setting the User Listing Base, I can see my list of users with their UPN listed under Username. However, verifying the source still fails. Any hints?
