• FederatedIdentityCaeTests.cs — Re-enabled ManagedIdentityWithFic_WithClaims_BypassesCache

Original prompt

Create a pull request to update Microsoft.Identity.Client (MSAL) from 4.82.0 to 4.83.1 and re-enable the Managed Identity CAE-related tests that were previously skipped for issue #3669.

Changes Required

1. Bump MSAL package version

   • File: Directory.Build.props
   • Change <MicrosoftIdentityClientVersion> from 4.82.0 to 4.83.1

2. Update binding redirects to match the new version

   • File: tests/DevApps/aspnet-mvc/OwinWebApp/Web.config
     • Update bindingRedirect for Microsoft.Identity.Client (2 instances) to oldVersion="0.0.0.0-4.83.1.0" and newVersion="4.83.1.0"
   • File: tests/DevApps/aspnet-mvc/OwinWebApi/Web.config
     • Update bindingRedirect for Microsoft.Identity.Client (2 instances) to oldVersion="0.0.0.0-4.83.1.0" and newVersion="4.83.1.0"

3. Re-enable Managed Identity CAE tests (remove Skip for issue 3669)

   • File: tests/Microsoft.Identity.Web.Test/ManagedIdentityCaeTests.cs
     • Remove Skip = "See https://github.com/AzureAD/microsoft-identity-web/issues/3669" from:
       • ManagedIdentity_ReturnsBearerHeader
       • ManagedIdentity_WithClaims_HeaderBypassesCache
       • UserAssigned_MI_Caching_and_Claims
       • SystemAssigned_MSI_Forwards_ClientCapabilities_InQuery
   • File: tests/Microsoft.Identity.Web.Test/FederatedIdentityCaeTests.cs
     • Remove Skip = "See https://github.com/AzureAD/microsoft-identity-web/issues/3669" from ManagedIdentityWithFic_WithClaims_BypassesCache

This updates the MSAL version to 4.83.1 (https://www.nuget.org/packages/Microsoft.Identity.Client/4.83.1) and re-enables the previously skipped tests.

The following is the prior conversation context from the user's chat exploration (may be truncated):

User: see this PR - I need you to create a new one based off of this - @AzureAD/microsoft-identity-web/pull/3745

Enable tests but use MSAL 4.83.1 https://www.nuget.org/packages/Microsoft.Identity.Client/4.83.1

Assistant: I'll create a new pull request based on PR #3745 that enables tests and updates MSAL to version 4.83.1. Let me first examine the current PR to understand what changes were made.

Assistant: I've reviewed PR #3745. Now I'll create a new PR based on it, updating MSAL to version 4.83.1 instead of 4.82.1-preview2 while keeping the test re-enablement changes.

Assistant: I've successfully created a new pull request to update MSAL to version 4.83.1 and re-enable the Managed Identity CAE tests. The PR will:

1. Update the MSAL version in Directory.Build.props from 4.82.0 to 4.83.1
2. Update binding redirects in both OwinWebApp/Web.config and OwinWebApi/Web.config to version 4.83.1.0
3. Re-enable all 5 tests that were skipped due to issue Disabled MSI tests due to instance discovery changes in MSAL for MSI #3669:
   • 4 tests in ManagedIdentityCaeTests.cs
   • 1 test in FederatedIdentityCaeTests.cs

The pull request is now open in the AzureAD/microsoft-identity-web repository with all the necessary changes based on the pattern from the original PR #3745.
