SAML Azure mappings

I'm trying to setup SocialCast to use SSO against Azure AD. I have everything working except I'm unable to map the fields for first name, last name, and email address. I know authentication is working because the logs on Azure confirm it, but I know I'm unable to pass names and email addresses because the test from SocialCast has blanks where there should be a name

This is what I need to fill out

I've tried a bunch of different things in those fields, but none of them seem to work.

Here's a screenshot of the test from Socialcast
