AzureAD: reached an unknown page within the authentication process

[jf13]

Hi, Is there any update on this?

There was old topic about it which is closed but it doesn't look like it was resolved.
#628

I am seeing the same error on version 2.36.13:

reached an unknown page within the authentication process provider=AzureAD
failed get SAMLAssertion

Check below:
