About Shibboleth, you should use a configuration template instead of manually copying files into the server structure.

I've read this page http://doc.nuxeo.com/display/ADMINDOC56/Configuration+templates several times over the last month and can't figure out how this works. Can anyone give me some more hints about how I would go about creating a configuration template for shibboleth?
