As far as I understand on the Single Sign On userid and publicusername are unique identifiers of the users. What would be the best approach to implement SSO if I don't have unique usernames?
I have userid and public name (which are none unique and cannot be identifier but should be displayed next to the question or comment/answer). My best thought is to run DB query on qa_get_users_html() and print the names I need with a link to /qa/<userid>.
In such case userid and publicusername will be the same on qa_get_logged_in_user(), qa_get_userids_from_public() and qa_get_public_from_userids().
Is there any better approach?
