Microsoft PowerPlatform Dataverse Nuget SDK always shows 'HTTP request was forbidden with client authentication scheme 'Anonymous''

Question

So I am trying to follow this section here: https://learn.microsoft.com/en-us/power-apps/developer/data-platform/org-service/quick-start-org-service-console-app

Whether I use a connection string like:

OAuth:

"AuthType=OAuth;UserName={_userName};Password={_password};ClientId={_clientId};ClientSecret={_clientSecret};
Authority=https://login.microsoftonline.com/{_tenantId};Url={_url};RedirectUri=http://localhost;";

or ClientSecret:

$"AuthType=ClientSecret;ClientId={_clientId};ClientSecret={_clientSecret};
Authority=https://login.microsoftonline.com/{_tenantId};Url={_url};";

I keep getting the error:

I check my Entra settings and followed what I thought was required for 'ClientSecret'

and check API permissions:

as well as the secret got generated:

I even added my proxy user as an owner:

I have no idea what is going wrong as it says anonymous and it's clearly I am using a dedicated application but is there something on dataverse that also needs to be set up? I have the user I am invoking there already setup but I am not sure if you can setup the Entra Auth setting anywhere.

Any help is much appreciated.

Answer 1

the App you are using "Dataverse Application" in azure app. That needs to be associated with Dataverse (aka. Power Platform). Create an application user using "Maker Portal" (https://make.preview.powerapps.com). Select your environment and go to Application User. Provide your "Client ID" and assign it a Dataverse Role. Now when you authenticate it should go through. Because this is not 401, this is 403 (Forbidden access)
