Is it possible to use the TFS SDK to query and edit Server Access Levels (Stakeholder, Basic, Advanced)

Question

I'm currently using TFS 2013 (On Premise). I'm unable to find a way to programmatically query the lists of 'Stakeholder', 'Basic' and 'Advanced' users, set in the 'Access Levels' tab of the Control Panel at server level, or, given a valid TeamFoundationIdentity, find out what their corresponding access level is. Is it possible to do this?

I am quite familiar with using the SDK, although only reasonably so when looking up users and security. As an example, I know how to list all Project Collection Valid Users across the server.

TfsConfigurationServer configurationServer

IIdentityManagementService ims = configurationServer.GetService<IIdentityManagementService>();

TeamFoundationIdentity[][] identities = ims.ReadIdentities(IdentitySearchFactor.AccountName,
        new[] { "Project Collection Valid Users" }, MembershipQuery.Expanded, ReadIdentityOptions.ExtendedProperties);

Any help will be greatly appreciated, thanks.

You can read access level of a user using REST Client API.

String collectionUri = "https://{account}.visualstudio.com";
VssCredentials creds = new VssClientCredentials();
creds.Storage = new VssClientCredentialStorage();
VssConnection connection = new VssConnection(new Uri(collectionUri), creds);
var licensingHttpClient = connection.GetClient<LicensingHttpClient>();
var accountEntitlement = licensingHttpClient.GetAccountEntitlementAsync().Result;
var license = accountEntitlement.License;

No, it’s impossible.

It seems there is no official document about how to querying and edit Server Access Level using TFS API.
