I'm glad to hear that - especially that you've managed to configure everything without external help.
It proofs that it's less complicated than most fellows are afraid of.
Yes, SAML 2.0 is powerful and thus there are many options to choose from - but on the other hand it's a standard and by exchanging the metadata between IdP and SP a lot of configuration steps can be automated.
Configuring SPNego is also not that difficult - and we are working on making it even more simple (including the SNC setup).
