Other? - please describe;

Is this a new or existing app?

The app is in production. Trying to add MSAL for login using Azure and Facebook.

Repro

//Login
            AuthenticationClient = PublicClientApplicationBuilder.Create(Constants.ClientId)
            .WithIosKeychainSecurityGroup(Constants.IosKeychainSecurityGroups)
            //.WithIosKeychainSecurityGroup("*")
            .WithB2CAuthority(Constants.AuthoritySignin)
            .WithRedirectUri($"msal{Constants.ClientId}://auth")
            //.WithRedirectUri($"https://jwt.ms")
            .Build();

Expected behavior Login using Azure AD or Facebook works as expected.

Actual behavior Login only works in DEV when using .WithIosKeychainSecurityGroup(“*”). This does not work when deployed to the app store. If changed to .WithIosKeychainSecurityGroup(“com.microsoft.adalcache”) or with my identifier, error occurs:

The application does not have keychain access enabled in Entitlements =.plist.

Possible Solution

.WithIosKeychainSecurityGroup(“*”).
