OpenID Single Sign On Implementation
I need to ask a very quick question. You know, in many cases, on a a thirdparty custom built site, we have to use foreign keys to associate different types of information with user. For example, in a blog application, we associate UserID with Post records.
My question is **how do we get a UserID if authentication is done using OpenID???**.

I am new to Single Sign On solutions so I want to think in right direction. Your response will really really appreciated.

Thanks
