If they're both Shibboleth, then the issue is the metadata, plain and simple.

Then that in fact is not true. You probably are modifying the wrong metadata or it isn't being successfully loaded. Or there's a duplicate metadata entry for the SP trumping the one you're changing. This is a metadata issue.
