Relevant Code Snippets

I've uploaded a repo with the full code here https://github.com/jeromechrist/repro-step-b2c

This is based on the sample here https://github.com/Azure-Samples/ms-identity-javascript-angular-tutorial/issues/7#issuecomment-854313384

Reproduction Steps

I've recorded the issue here, you can see that on Edge (first) the issue doesn't happen, then in Safari it happens every time.

The step is to basically try to access a resource, here the Web API, protected by an Azure AD B2C instance.

Expected Behavior

I should be able to access the resource

Thank you for bringing this to our attention. I read through the issue posted in the angular-tutorial repo and will get back here once we can find a root cause.

jeromechrist commented 3 years ago

alright, thank you

derisen commented 3 years ago

Adding the repo for reproduction. cc @jasonnutter checking for interaction_in_progress in the component where looping happens doesn't seem to have an effect.

@jeromechrist Can you capture the network trace using Fiddler and send it to us? You can use the email under my profile.

jasonnutter commented 3 years ago

General comment: apps using redirects with MSAL Angular must make sure to not perform any action (e.g. http request) that might result in an interactive MSAL request (e.g. redirect to the login page) until any previous interactions have completed. This can be done by subscribing to the $inProgress subject and waiting for InteractionStatus.None. Not doing so can result in login loops.

Details here: https://github.com/AzureAD/microsoft-authentication-library-for-js/blob/dev/lib/msal-angular/docs/v2-docs/redirects.md

Example: https://github.com/AzureAD/microsoft-authentication-library-for-js/blob/dev/samples/msal-angular-v2-samples/angular11-b2c-sample/src/app/app.component.ts#L35-L43
