Login with Microsoft AD authentication using signInWithWebUI is not successful.

[bbdev9805]

Describe the bug

There is a pattern in which login with Microsoft AD authentication using SignInWithWebUI is not successful. This issue occurs when Microsoft Intune Conditional Access is set to require an app protection policy. This setting requires authentication to be performed on Edge. However, signInWithWebUI uses ASWebAuthenticationSession. Therefore, Microsoft authentication screen will appear asking to launch in Edge. After launching Edge, a HostedUI error screen is displayed in the browser. After that, if entering the email address on the Hosted UI screen, the app will call back. When returning to the app, the Microsoft authentication screen remains displayed.

Steps To Reproduce

Steps to reproduce the behavior:
1. Open the app and login with Hosted UI
2. Launch Edge from the Microsoft authentication screen
3. Enter the email address on HostedUI
4. Authentication not completed

Expected behavior

No error occurs in HostedUI after launching Edge from the Microsoft authentication screen. Then, return to the app, close the Microsoft authentication screen, and complete the sign-in.

@bbdev9805 Are you still facing the issue?

[bbdev9805]

@harsh62 Yes, This issue has not been solved.

[harsh62]

@bbdev9805 So I am able to create a very similar environment that you have, and not able to reproduce the issue. Would you be able to provide verbose logs when this issue happens? You can enable verbose logging to the console by doing this before calling Amplify.configure:

Amplify.Logging.logLevel = .verbose

Additionally, can you also provide your amplifyconfiguration.json file redacted all the sensitive information.

Lastly, have you made sure that the redirect URI has been setup correctly in the app?

[bbdev9805]

@harsh62 How should I provide the logs and the amplifyconfiguration.json file? The redirect URI is set up correctly. The issue occurs when authentication is required on Edge, as described below. If Microsoft Intune Conditional Access is not configured, the ASWebAuthenticationSession appears and the sign-in completes successfully.

This issue occurs when Microsoft Intune Conditional Access is set to require an app protection policy. This setting requires authentication to be performed on Edge.

Thank you @bbdev9805 . I will try to setup the account with the setting that you provided and see if I can recreate the issue.
