Hi Jose,
I think in order to achieve this you need to run all of your logins through a single domain, once a login has been confirmed you set a cookie on a per-domain basis. You could pass around a session identifier and set cookies as the user goes from one domain to the next. If a user hits a domain without the session identifier you could pass them through the login domain (with details on where to send them back to) which will automatically detect if they are logged in and return the session identifier. You could likely include this login box using an iframe, the iframe could perform the login (or detect that they are logged in) through your central domain and redirect the parent window, or set a javascript variable, or call a javascript function. You cant achieve this through XHR since you cant call other domains.

I would like to construct all my applications base on one single account administration, like GOOGLE and YAHOO... at these sites, you can login into a service and use other services as well with a single account... I would like very much to discuss this with you guys! Suggestions? Regards, José
