Application Token based Request returning not 401 Unauthorized

[manthena]

I have a background application which is supposed to connect to Data Catalog and fetch information related to a table. Since its a background application, I cannot have any user intervention to authenticate the Data Catalog request. So I am trying to authenticate using ClientID and ClientSecret instead.

`string authorityUri = "https://login.microsoftonline.com/{adtenanthere}";
string resourceUri = "https://datacatalog.azure.com";
string clientId = "{clientidhere}";
string clientSecret = "{clientsecrethere}";

AuthenticationContext authContext1 = new AuthenticationContext(authorityUri, false);
ClientCredential credential = new ClientCredential(clientId, clientSecret);
AuthenticationResult authResult = authContext1.AcquireTokenAsync(resourceUri, credential).Result;
string token = authResult.CreateAuthorizationHeader();`

Getting the token using this method is being successful, however when I use this token for the Data Catalog API request, the request returns "401 - Unauthorized: Access is denied due to invalid credentials. You do not have permission to view this directory or page using the credentials you supplied".

Please suggest what I could be missing here!

Hi @rajaragothaman, I never got this issue resolved. Meanwhile our design changed, so we are no longer using Azure Data Catalog.

If you have this issue resolved, please confirm the solution. It will be useful for everyone.
