C# Azure AD - Getting List of Users and current user's title - Stuck in loop

Question

User-1662920186 posted

So I am trying to basically check Azure AD for the current user's title and provide a drop down list of all the users in Azure AD but I keep getting a timeout. 

Any suggestions would be helpful. Here is what I have so far:

private async Task<bool> getInfo() { string currentUser = HttpContext.Current.User.Identity.Name; string tenantId = "tId"; string applicationID = "appId"; string applicationKey = "appKey"; AzureGraphAuthenticationProvider graphAuth = new AzureGraphAuthenticationProvider(); //This class is defined in bradley.cs and gets the token graphAuth.tenantId = tenantId; graphAuth.applicationID = applicationID; graphAuth.applicationKey = applicationKey; GraphServiceClient graphClient = new GraphServiceClient(graphAuth); //sets graph client using previously obtained token User user = await graphClient.Users[currentUser].Request().GetAsync(); return true; }

And I went into my azure portal, clicked on my "Azure Active Directory", then "App Registrations", registered a new application, grabbed the applications ID, and created a key and saved it. The app has access to Azure AD but it still just spins and eventually times out.

Hi,

A timeout would me make think first about a firewall or proxy issue. It happens on GraphClient or could it be inside AzureGraphAuthenticationProvider instead ?

I would perhaps try a search based on the error message as well as the method in which it happens (see the call stack). It could help finding a post from someone who had the same issue.

Hi MethodDev,

Please use Fiddler to trace the requests  check the detailed error message . In addition ,since you are using Microsoft Graph .NET Client Library , please refer to below link for code samples :

I am looking into that currently to see if that is what is causing the issue.

This is the "AzureAgraphAuthenticationProvider":

public class AzureGraphAuthenticationProvider : IAuthenticationProvider
{
public string tenantId { get; set; }
public string applicationID { get; set; }
public string applicationKey { get; set; }

public async Task AuthenticateRequestAsync(HttpRequestMessage request)
{

HttpClient client = new HttpClient();

ClientCredential credential = new ClientCredential(applicationID, applicationKey);

var authenticationContext = new AuthenticationContext("https://login.microsoftonline.com/" + tenantId);
var authenticationResult = authenticationContext.AcquireToken("https://graph.microsoft.com/", credential);

string token = authenticationResult.AccessToken;

request.Headers.Add("Authorization", "Bearer " + authenticationResult.AccessToken);
}
}

I've not used fiddler before so I am unsure of what I am looking at.

Update:

When I switch my async to async void instead of Task<bool> it runs but I get an insufficient privileges message. So maybe you can't have these ran as async Task<bool>?

authenticationResult could just return the type name rather than the expected token. I checked some code and if you have this method try :

request.Headers.Add("Authorization", authenticationResult.CreateAuthorizationHeader());

Else if you suspect a value is wrong, look at the value you are using to see if this is what you expect.

Not sure what you mean by a "compact error" ? IMO it's easier to just post the error message so that others don't have to guess which error you have.

I think its overall permissions, switched from "public async task<bool>" to "public async void" and was able to get it to load but with an insufficient privileges error which I should be able to correct today. Now I am curious why it gets stuck when I set it to "public async task<bool>", odd.

How do you call getInfo when it returns a Task<bool> ?

I am just doing a "bool x = getInfo().Result", is that incorrect? When I use that is just spins until it times out. Still getting used to switching to async.

So when I use it as a void it works and I get a value from AAD but when I run it as a task<bool> it locks up.

Here is the solution for anyone that is curious:

Task.Run(async () => { return await getInfo(); }).Result;
