Hi @ioanmo226, I haven't fully tested implementation yet, but can you please also add ui test for checking if correct auth modal is shown when custom IdP is configured and Enterprise Server error is received. It's quite important functionality, so better have it tested to be sure that it works well after future code changes.

[ioanmo226]

Ohh. Yep
It's necessary to add UI test.
Let me add that.

Well done, works great 👍
