Describe the bug
I followed the example tutorial for Microsoft SSO integration, double or triple checked.. And when i try to login using Microsoft i get that error:

I really checked everything, but it seems the callback url does not work when logging in..

Things to know:

yea that's strange, because you have indeed set the callback url yet MS somehow thinks its missing. Maybe open a support ticket with MS and ask why it's not being saved.
