Dotnetopenauth single sign on with custom identity provider

I'm trying to setup the DotNetOpenAuth samples to have a working SSO
solution with a custom provider. I'm using OpenIdProviderMvc sample
project which appears to be working fine.
My problems is setting up the "consumer", in this case the
OpenIdRelyingPartyMvc sample project, I cannot configure it to use the
OpenIdProvider.
I tried to setup an endpoint on the consumer's web.config like this:
<trustedProviders rejectAssertionsFromUntrustedProviders="true">
<add endpoint="http://localhost:4864/OpenID/Provider" />
</trustedProviders>
But all I get is "No OpenID endpoint found." errors (actually, I'm not
quite sure on what to put on the OpenID box...)
This project is virtually undocumented. Can someone point me in the right
direction?
At least to have a provider and consumer working and talking to each other?
