Managed identity error

[markgould]

I'm attempting to use TokenProvider.CreateManagedServiceIdentityTokenProvider() to login and I'm getting an error. This is running through Visual Studio or from a command prompt. I haven't attempted to deploy to an actual container yet until I can get this to work.

<Error><Code>401</Code><Detail>MalformedToken: Invalid authorization header: The request is missing WRAP authorization credentials. TrackingId:0910eebc-76b3-414a-b45d-fabca4df9477_G33, SystemTracker:[namespace].servicebus.windows.net:[queue], Timestamp:11/9/2018 4:36:45 PM</Detail></Error>

Here is the request header:

GET /[queue]?api-version=2017-04&enrich=False HTTP/1.1
Authorization: [jwt]
UserAgent: SERVICEBUS/2017-04(api-origin=.NETStandard,Version=v2.0;os=Microsoft Windows 10.0.17134 ;version=3.1.0.0;product=Microsoft.Azure.ServiceBus)
Host: [namespace].servicebus.windows.net

I confirmed Azure Service Authentication has the right account set in VS and I decoded the JWT and it does appear to be correct (pointing to my local developer account)

Am I missing something?

Here is a simple repro:

        static void Main(string[] args)
        {
            var token = TokenProvider.CreateManagedServiceIdentityTokenProvider();           
            var client = new ManagementClient("sb://namespace.servicebus.windows.net/",  token);
            var desc = client.GetQueueAsync("QueueName").Result;
        }

Hi Mark, did you get any where with this? I have hit the exact same problem. Can use the QueueClient with almost identical code successfully, however the ManagementClient is having non of it.

Unfortunately not. Hopefully we can get an answer here at some point.

I am also hitting this issue, I attempted to deploy the code to an Azure Function and see the same issue I saw locally.

ManagementClient and old client's NamespaceManger doesn't support MSI right now in preview phase. The service needs few more changes. Right not MSI can be used only with the ARM based APIs for management.
