[OpenID] Defn of Absolute URL?

"OP Endpoint URL: 

The URL which accepts OpenID Authentication requests, obtained by
performing discovery on the the User-Supplied Identifier. This value
MUST be an absolute URL. "



What is an absolute URL?

Is ldap://127.0.0.1/searchop=subtree,<match=attributeslist>, dn=<some
walled garden DN>  an "absolute URL"?

-- understanding that if it is, the addressed resource/agent may chain
off the search operation as a proxy, if the ldap listener is but a front
end to a real X.500 server?
