Hi, I wonder what other people think about following. I want to build a system that will authenticate users across multiple sites, so users have to log in only once on one site, and then just click on a link and go to another site with their credentials. All sites are Quixote applications on different subdomains on one Apache server with mod_scgi. PostgreSQL will be used for sessions. What is the strategy for creating thing like that? Has anyone done it before in Quixote? Any tips would be greatly appreciated :-) -- Ksenia
