Great news! I figured out how to reproduce the error. If I try to log in as “Sudoman” instead of “sudoman”, then this error appears. Our CAS server (i’m not referring to the CAS SSO service connected with Discourse) allows people to log in lto our systems like that. In any case, presuming that the SSO provider is passing the user to Discourse with the user name of “Sudoman”, is this error message the desired behavior in Discourse, or is it a bug? In my case, it would make sense to allow the user to log in, but in other systems, that could be a different user who is trying to log in. I tried creating an account with capitalized letters in the user name, and an account was created with the same capitalization. Trying to log in again with all lower case letters caused an error. That makes sense to me. Maybe it would make sense to create a resource that lists the list of possible causes that produces this error message. It would help systems administrators track down the issue when this happens to their users.
