Establish UserEndpoint without Credentials in UCMA 4

Question

How can I establish a UserEndpoint without Credentials? I read somewhere that it should be possible if the Application/ApplicationServer is trusted by the Lync Server. This is the case, but it does not seem to work. I always get the Exception

No matching credential found for the realm.

Fist set-up CollaborationPlatform using ProvisionedApplicationPlatformSettings:

ProvisionedApplicationPlatformSettings settings = new ProvisionedApplicationPlatformSettings("UCMA 4", _appID);
CollaborationPlatform  _collabPlatform = new CollaborationPlatform(settings);
_collabPlatform.RegisterForApplicationEndpointSettings(this.Platform_ApplicationEndpointOwnerDiscovered);
// Initialize and start-up the platform.
_collabPlatform.BeginStartup(EndPlatformStartup, _collabPlatform);

Then Set-up your application endpoint in Platform_ApplicationEndpointOwnerDiscovered callback method. then once it all done you can call this method and set-up UserEndpoint without credentials:

Use this method to create UserEndpoint
private UserEndpoint CreateUserEndpoint(CollaborationPlatform  _collabPlatform, String _SIP)
{
    try
    {
        UserEndpointSettings _settings = new UserEndpointSettings(_SIP, _serverFqdn);
        _settings.SupportedMimePartContentTypes = new ContentType[] { new ContentType("text/html"), new ContentType("text/plain") };
        _settings.AutomaticPresencePublicationEnabled = true;
        UserEndpoint _userEndpoint = new UserEndpoint(_collabPlatform, _settings);
        _userEndpoint.EndEstablish(_userEndpoint.BeginEstablish(null, null));

        return _userEndpoint;
    }
    catch (Exception exx)
    {
        Console.WriteLine("\n" + _SIP + "CreateUserEndpoint : " + exx);
        return null;
    }
}
