Hi: I think it would be a good idea to provide administrators who use one Drupal installation for multiple sites and share users and sessions across those sites (via $db_prefix) with a new option that would let users who log into one of the sites to be automatically logged into some or all of the other companion sites. I'm envisioning this working by adjusting user_login() function in user.module. Once a login is successful, have the function send out PHPSESSID cookies for the desired sites, each containing the same session id. Your thoughts? --Dan -- T H E A N A L Y S I S A N D S O L U T I O N S C O M P A N Y data intensive web and database programming http://www.AnalysisAndSolutions.com/ 4015 7th Ave #4, Brooklyn NY 11232 v: 718-854-0335 f: 718-854-0409
