Incorrect validation for Redirect URI in Entra ID App registrations

Question

Incorrect validation for Redirect URI in Entra ID App registrations

Baptiste VIALA 0

Hello,

Please see following screenshot:

a) This is a correct URI per RFC3986

b) It represents the app entry point in a React Native app

c) Such URI is supported by other OIDC providers

d) For reasons specific to React Native development I do not want to use a specific callback route such as "myapp://auth". (iOS does not redirect after a browser sign in)

Please fix

Hello Baptiste VIALA,

If you just enter myapp:// , it will show must be a valid URI:

Hence, use a redirect URL with host such as myapp://callback/auth or myapp://auth

Let me know if any further queries - feel free to reach out!
