I feel like I might be missing something here. I have an AD/Internal user source created that I can verify as a user source an get user attributes from. I have also created an IdP that uses the AD/Internal as a User Source, have a Security Level defined, user grants set for a user and roles set for that user on the provider. I try to do a Test Login, or login through perspective and when I put in the correct user information I end up with an unauthenticated user with a return that says “No IdP Response Data” when trying the Test Login from the IdP configuration page. Is this a configuration issue on my end in user attribute mapping or some other place? I will note that I have the same configuration for an IdP that uses an internal Ignition User source that seems to work. ---

Could be an attribute mapping misconfiguration for the user name or id attribute. Try setting the `gateway.WebAuthSessionImpl` and `gateway.IdpAdapter` logs to debug and login again to see if anything more useful prints to the logs. ---

If you go to your AD / Hybrid user source in the Users, Roles section of the gateway config web interface, and click on manage users, does user `greenc` show up on that list? ---

It appears as though ‘greenc’ needs to be ‘GreenC’ for this to work. I am able to use greenc and put in a password and it navigates me back to the project view from there, but unless I use ‘GreenC’ with the caps in place, the IdP fails. Is this a bug or do I need to enforce something when people are typing in their username? ---

Ah that explains it. It appears that during authentication, the username is case insensitive, but when we perform the redirect back to the application (in this case, test login), we are performing a case sensitive lookup of the user’s information to fill in the attribute mapper and that lookup is based on how the user entered their username in the login form (in a case-sensitive fashion). I’m going to mark this as a bug on our side. We’ll figure out a better way to handle this. Thanks for sharing the issue. ---

Not sure what exactly was fixed here, but the case-insensitive login wasn't fixed. Will this be addressed? ---

The fix implemented six years ago was strictly within the user source layer; can you expand more on where you're having issues? ---

Just that logging in is case-sensitive for the username. e.g. if the username defined is "nick" then you can't login with "Nick". Noting that most phones would input the latter as they auto-capitalise non-password fields. It's always a confusion point for operators which ultimately leads to spurious "I can't login" support calls because they have the wrong letter case. ---
