Openstack.Net SDK cannot access services

Question

We've setup an OpenStack system on our own hardware installing all components, with everything seemingly fine as we've created networks and VMs through the web interface.

I'm trying to use openstack.net SDK to do things programatically. I seem to be able to Authenticate fine using a username and password, but when it comes to accessing other services that are installed, we get errors suggesting the API endpoints aren't available to the user.

The code we're using is below which works fine until the CreateServer line at which point I get the error

"Unable to authenticate user and retrieve authorized service endpoints."

 Uri baseUrl = new Uri("http://mycloudip:5000/v2.0");
 CloudIdentity cloudId = new CloudIdentity()
            {
                Username = userName,
                Password = password
            };
 CloudIdentityProvider cip = new CloudIdentityProvider(cloudId, baseUrl);
 UserAccess ua = cip.Authenticate(cloudId);

 CloudServersProvider provider = new CloudServersProvider(cloudId);

 Metadata metaData = new Metadata(); // Add some metadata just because we can
 metaData.Add("Description", "Example 4 - Getting Started");

 string serverName = "Example4";
 string imageId = "48df4181-040e-4821-8723-d9e4ba908d2f";
 string flavorId = "3";

NewServer newServer = provider.CreateServer(serverName, imageId, flavorId, DiskConfiguration.Manual, metaData);

I can see all the service urls in the Access and Security >> API Endpoints section whilst logged on as the same user in the dashboard, but UserAccess.ServiceCatalog doesn't seem to be populated with anything.

Any help or pointers much appreciated.

The default IIdentityProvider used by the CloudServersProvider implementation in openstack.net SDK 1.3.2.0 is designed around the authentication requirements for Rackspace. In order to authenticate against a different OpenStack-compatible installation, you'll need to follow the steps described in the following documentation:

OpenStack Authentication (openstack.net API Reference Documentation)

The following is an excerpt of the current documentation:

This page describes the process for authenticating against reference OpenStack installations, including but not limited to DevStack and the Rackspace Private Cloud.

Usage Notes

Client authentication against a reference OpenStack installation requires the following.

Create an instance of CloudIdentityWithProject and initialize its properties with the desired authentication credentials. The CloudIdentityWithProject credentials class allows the tenantName and tenantId properties described in the OpenStack documentation to be defined.

Create an instance of OpenStackIdentityProvider , and pass the previously created credentials to the constructor.

When creating a service provider instance, such as CloudFilesProvider or CloudQueuesProvider , pass null for the CloudIdentity parameter and the identity provider from the previous step as the IIdentityProvider parameter.

Limitations

The OpenStackIdentityProvider only supports authentication using username and password credentials, along with optionally specifying the tenant name and/or tenant ID (referred to as the project name and ID starting with the Identity Service API v3).
