OpenID now uses hash-code for confirmation and provides some level of security.

OpenId cannot be used to login as users who haven't used OpenID registration yet.
Admin now can view and edit user's information: email, first name, last name and roles.
Kind of fixed stupid, stupid error (There were only one admin, one teacher and one student in the datebase. Adding another one revoked previous owner's role.)
