Using Net::SAML2 to do SP-initiated SSO with ADFS

neilb has asked for the wisdom of the Perl Monks concerning the following question:

Has anyone got experience of doing SAML2-based single sign-on (SSO) using the Net::SAML2 module talking to Microsoft's ADFS as the identity provider?

I've used Net::SAML2 with other SAML providers, but am struggling with ADFS, and feel like I'm just banging my head against it.

Cheers, Neil
