This is not in fact any easier but certainly possible.

That just means that. The SP has no metadata for the IdP.

If that is the entityID (or the URL for metadata) of the IdP then it
does not match the above entityID which ends in "/idp/shibboleth".

Also maybe the machine does not resolve the correct hostname or virtal
host from localhost itself.

If you just want to make sure everything works cofigure the SP to use
metadata for the IdP from the local file system, by default from

Not that fetching metadata from the entityID itself is recommended for
production use, but try to fetch that URL from the machine itself,
e.g. using curl or wget (or elinks or telnet or whatever).
