Get Azure Active Directory Token with username and password - azure

Question

I'm trying to authenticate my client using AAD and automate this using a Windows Service. In AAD .NET SDK, There's two methods, AcquireTokenAsync and AcquireToken, but i can't use either of these methods, the await call will stay forever with no response, and when i do something like this:
result = authContext.AcquireTokenAsync(resourceHostUri, clientId, new UserCredential(hardcodedUsername, hardcodedPassword)).Result;
The object returns a status of Waiting for Activation & Code 31..
Now, Is there anyway to acquire the token using hardcoded username and password?
My full code:
string hardcodedUsername = "username";
string hardcodedPassword = "password";
string tenant = "tenantId#onmicrosoft.com";
string clientId = "clientId";
string resourceHostUri = "https://management.azure.com/";
string aadInstance = "https://login.microsoftonline.com/{0}";
string authority = String.Format(CultureInfo.InvariantCulture, aadInstance, tenant);
authContext = new AuthenticationContext(authority);
AuthenticationResult result = null;
try
{
result = authContext.AcquireTokenAsync(resourceHostUri, clientId, new UserCredential(hardcodedUsername, hardcodedPassword)).Result;
}
catch (Exception ex)
{
System.Diagnostics.Debug.WriteLine(ex.Message);
}
return result;
I'm trying to get access to Azure API.
UPDATE 1:
I got this in the output when i tried to await the call, i think this might help:
Microsoft.IdentityModel.Clients.ActiveDirectory TokenCache: Looking up cache for a token...
Microsoft.IdentityModel.Clients.ActiveDirectory TokenCache: No matching token was found in the cache
Microsoft.IdentityModel.Clients.ActiveDirectory d__0: Sending user realm discovery request to 'https://login.microsoftonline.com/common/UserRealm/username?api-version=1.0'
Microsoft.IdentityModel.Clients.ActiveDirectory d__4: User with hash '***' detected as 'Federated'

How to get current token from Azure ActiveDirectory application
// Get OAuth token using client credentials
string tenantName = "GraphDir1.OnMicrosoft.com";
string authString = "https://login.microsoftonline.com/" + tenantName;
AuthenticationContext authenticationContext = new AuthenticationContext(authString, false);
// Config for OAuth client credentials

ClientCredential clientCred = new ClientCredential(clientId, key);
string resource = "https://graph.windows.net";
string token;
try
{
AuthenticationResult authenticationResult = authenticationContext.AcquireToken(resource, clientCred);
token = authenticationResult.AccessToken;
}
catch (AuthenticationException ex)
{
Console.ForegroundColor = ConsoleColor.Red;
Console.WriteLine("Acquiring a token failed with the following error: {0}", ex.Message);
if (ex.InnerException != null)
{
// You should implement retry and back-off logic according to
// http://msdn.microsoft.com/en-us/library/dn168916.aspx . This topic also
// explains the HTTP error status code in the InnerException message.
Console.WriteLine("Error detail: {0}", ex.InnerException.Message);
}
}

Please try the following:
static void Main(string[] args)
{
Task<AuthenticationResult> t = getAccessToken();
t.Wait();
var result = t.Result;
Console.WriteLine(result.AccessToken);
Console.WriteLine("Please any key to terminate the program");
Console.ReadKey();
}
public static async Task<AuthenticationResult> getAccessToken()
{
string hardcodedUsername = "username";
string hardcodedPassword = "password";
string tenant = "tenant.onmicrosoft.com";
string clientId = "clientId";
string resourceHostUri = "https://management.azure.com/";
string aadInstance = "https://login.microsoftonline.com/{0}";
string authority = String.Format(CultureInfo.InvariantCulture, aadInstance, tenant);
var authContext = new AuthenticationContext(authority);
AuthenticationResult result = null;
try
{
result = await authContext.AcquireTokenAsync(resourceHostUri, clientId, new UserCredential(hardcodedUsername, hardcodedPassword));
}
catch (Exception ex)
{
Console.WriteLine(ex.StackTrace);
System.Diagnostics.Debug.WriteLine(ex.Message);
}
return result;
}
What I have done is made getAccessToken() method async and inside that the code is made to wait to get the token when you call authContext.AcquireTokenAsync.
