Anyone pulling a linked calendar feed from Slate?

Anyone here have success pulling a public iCal feed URL from Slate (admissions CRM) into LW as a Linked Calendar? I’m trying to set that up so admissions info sessions appear on our business school’s calendar (and directly link back to the Slate event page) but the iCal feed our admissions director copies from Slate seems to be tied to her admin login such that all of the events redirect the user to a Slate SSO login screen. Slate’s pretty popular so just wondering if anyone else has figured this out.
