Rails - Jan 2011 - Login connection between two websites

Hello everybody,

Guys, i''ve got a problem that i actually don''t know if it can
be solved.

In my app, i was trying to do something like this: i would like that only
people that have account in another site ( my university site)  could use
some features of my website.

So my idea was when a user wants to log in into my site, i redirect to the
login page of my university site, and than, if he is logged in  the
university site, than he is logged in my website too.

I would like to know if this is possible, to get the information via cookies
or sessions ( i dont know nothing about networking... )

Does anybody have any ideas about this?

Thank you all,

Fernando

You can''t do that accessing cookie.

You could create a button with an authentification data so that the 
other website will receive the authentification data and can login a 
user.
