HELP
I am a brand new admin and I know nothing about the admin side of SalesForce.  Can someone explain to me how I can check if my org is using a single sign-on or HTTPS call outs?   I need to know if the default certificate retirement on 8/7/17 will affect my org before 8/7/17.   I've been reading about it but none of it makes sense to me.
