Hmm, well I'd be able to reconstruct or otherwise gain knowledge about 
the URL I want if I can get the entityID of the SP that requested the 
SLO. But I wasn't quite able to get that, although I'd imagine that 
information should be shared through SAML.

Any chance for me to at least get the entityID?

Thanks,
