Accessing Kerberos-secured service from iOS / Android using .NET MAUI

MCM AL 1

We developed an iOS/Android-App using Xamarin.Forms, now MAUI. We want to access a web service that's behind Kerberos authentication. Running our app on windows, this is no problem.

But when we try to access the service from an iOS or Android device, we get a 401 (Unauthorized) response.

Is there any way to authenticate against a Kerberos-secured service from iOS or Android?

The following official documentation could be helpful to you:

Kerberos Single Sign-on extension with Apple devices.

Kerberos for Chrome on Android.

In addition, since this question is closely related to the native platform, it is recommended that you go to the native support platform to ask questions:

Apple developer forums.

Android Community.

If the device is managed:

on iOS you will have to configure the SSO Kerberos extension (see https://support.apple.com/en-gb/guide/deployment/depe6a1cda64/web), this will make it transparent to your application.

on Android you can do the same using Hypergate Authenticator (see https://hypergate.com), this will also make it transparent to your application.

Without being managed I don't know of any solution.
