Call D365FO Service gives (401) Unauthorized error.

Posted on by Rudi Hansen 4,075

I am trying to get the code from the ServiceSample application from github to work, more specifically the JsonConsoleApplication code.

I have made the App Registration on Azure, and registered the application on the "Azure Active Directory applications" page in D365FO.

I changed these values in the ClientConfiguration.cs file, so they should be correct.

UriString = "https://[myazureserver].cloudax.dynamics.com/"
ActiveDirectoryResource = "https://[myazureserver].cloudax.dynamics.com"
ActiveDirectoryTenant = "login.windows.net/dev.onmicrosoft.com"
ActiveDirectoryClientAppId = "[Should be the right one from Azure]"
ActiveDirectoryClientAppSecret = "[Should be the right one from Azure]"

And in Program.cs line 25 i added the parameter true to GetAuthenticationHeader so it should use web authentication.

Now when I run the program i get the error "The remote server returned an error: (401) Unauthorized." in line 29 "using (var response = (HttpWebResponse)request.GetResponse())"

If I look at the Event Viewer under Dynamics / AX-WebApi I see this error "Web API Owin Authentication Configuration Missing Error", but I have no clue what that means.

Can anyone help me get this to work?

    Verify you Active Directory Tenant , you can check from Azure portal - portal.azure.com/

    Just exactly do i need from the Tenant?

    Are you referring to the value in ActiveDirectoryTenant, with I have set to "login.windows.net/dev.onmicrosoft.com" (Sorry corrected the error in my exiting post)

    But I see nothing but a Tenant ID on the Azure Portal, and that is a string not an url.

    YES Finally Hurrah :-D

    It has really been bothering me that I have not been able to solve this problem with the exiting guides I have so far been able to find.

    But the solution was then to replace my :

    ActiveDirectoryTenant = "login.windows.net/dev.onmicrosoft.com

    With :

    ActiveDirectoryTenant = "login.microsoftonline.com/[TenantId]/saml2"
