I'm trying out Azure AD, to allow users to authenticate with their Microsoft account on my website. Oauth2 works fine when the redirect URI is http://localhost:8080/callback, but it fails when I try to enter the "real" IDN URI (https://södermalmsskolan.com/callback) in the portal, saying that the URI is invalid. I have also tried entering the punycode version (https://xn--sdermalmsskolan-8sb.com) but without any success. Am I doing something wrong?
Thanks
Microsoft indeed has issues supporting a 17 years old standard.
I opened a support ticket, this is the answer:
Based on our investigation, i could notice that the Redirect URls with IDN domain and Punycode is not supported as of now
We have determined that we have ran into a product limitation and have no work around at this time.
