Hello,
I'm trying to figure out possible solutions for a problem. I'm
currently using openID to authenticate users, restricting to Google as
an identity provider (both gmail and Google Apps).
What I need to do is to obtain reliable user information before a user
logs in to the application. Use cas
Does a domain's user list contain an ID? We can't provide this ID to you
ahead of time.
I think for your use case, it's safe to use the email and handle the edge
case of someone changing their email.
