wasn't quite sure if 200 was the right thing here.

We can make it a 400, but it shouldn't really matter since it will just be shown in a browser? I guess it matters how we want it to show up in the logs?

If a user tries to do UI Auth via SSO, but uses the wrong account on the SSO IdP, try to give them a better error. Previously, the UIA would claim to be successful, but then the operation in question would simply fail with "auth fail". Instead, serve up an error page which explains the failure.
since we're hacking on this code anyway, may as well move it out of the cluttered AuthHandler.

Part of me wonders if this really needs to be a separate template or if we can use the sso_error.html
template?

I tried that to start with, but the phrasing of the sso_error.html template is very much geared to server-side or integration problems. This particular failure is really a user error, so the generic error wording didn't seem to fit.

If a user tries to do UI Auth via SSO, but uses the wrong account on the SSO IdP, try to give them a better error.
Previously, the UIA would claim to be successful, but then the operation in question would simply fail with "auth fail". Instead, serve up an error page which explains the failure.
I've also inlined
AuthHandler.complete_sso_ui_auth
while I'm in the area. Generally I think thatAuthHandler
has too much miscellaneous stuff in, and pulling things out of it will make things cleaner.
