I may have mis-interpreted the whole concept here. Im sorry for causing any confusion here but I have no idea what needs to happen here. Basically this company said we don't use shibboleth we have a SAML 2 endpoint. which is the url provided. That is all the gave me. Am i mistaking in thinking that the ProviderId is a shibboleth concept for shibboleth sp?
