Hey @reshmee011 , any chance you might be able to test out this auth mode ? Just saw you do some interesting stuff in this area and was wondering if you might be able to help here with the FIC approach, no pressure 😊
Appreciate any help in this.

@gautamdsheth : that's a very cool addition/feature. I will try to spare some time over the weekend to test it. Thanks so much to make the product better.

src/Commands/Base/TokenHandler.cs:265

• The XML doc comment for GetFederatedIdentityTokenAsync is copy-pasted from the workload identity method and does not match this method’s purpose or parameters. Update <summary> and <param> tags to reflect federated identity semantics and the actual method signature.

/// Returns an access token based on a Azure AD Workload Identity. Only works within Azure components supporting workload identities.

src/Commands/Base/ConnectOnline.cs:90

• The Url parameter is optional in the FederatedIdentity parameter set, but it’s required to form the resource URI. Mark it Mandatory = true to avoid null references when building the token scope.

[Parameter(Mandatory = false, Position = 0, ParameterSetName = ParameterSet_FEDERATEDIDENTITY, ValueFromPipeline = true)]

src/Commands/Base/PnPConnection.cs:408

• Replacing the original AuthenticationManager constructor call with CreateWithManagedIdentity(null, null, ...) drops the endpoint and header fallback logic. This will break MSI token acquisition outside your default environment. Restore or refactor the endpoint/header resolution.

using (var authManager = Framework.AuthenticationManager.CreateWithManagedIdentity(null, null, managedIdentityType, managedIdentityUserAssignedIdentifier))
