Hi, this is Mehedi. I'm not new here though, I had a merged PR a few months back and I was excited to see plone in this year's GSOC list.
Anyways, the SAML technology seems very fascinating and I would love to work on it and turn this feature into reality. The possible mentor is yet to be decided so I'm not sure who to talk to about this. Am I late? I hope not. Would love to have a chat on this! Thank you.
