I have two ADFS 2.0 proxies named auth.somedomain.no and two ADFS 2.0 servers named adfs.somedomain.no.
However, https://auth.somedomain.no/FederationMetadata/2007-06/FederationMetadata.xml does not expose https://adfs.somedomain.no/FederationMetadata/2007-06/FederationMetadata.xml
Should there be an official ADFS and ADFS proxy name?
The answer is yes. I made a change, so that all adfs and proxies use the same federation name, such as sso. The MS documentation is not very accurate in this regard.
