hi,

i would like to integrate openid authentication. now, my current setup  
is  
that the user has to go through my own registration & activation pages  
to  
get his profile active.

the way i understood eg railscasts etc to use openid and similar  
techniques,  
its up the app to decide whether the users can register and or do the  
login  
only via openid and similar.  
now, in case of the login only, how do i map existing users to the ones  
who  
are loggin in via openid & similar (looked into openid-selector)?

maybe im overseeing something,

thx  
tom
