I installed the Joomla to eGroupware Single Sign-On
(http://extensions.joomla.org/extensions ... 22/details). Its web page is in Portuguese, so I may have misintepreted the Yahoo translation. However, when I export the users, this component only shows me the user 'admin' as being available for export. The other users aren't shown, although they appear in both the Joomla and Community Builder user lists. According to the web page, the component doesn't export the admin user for security reasons, but it gives me only this user. When that user is exported, clicking on a menu item for eGroupware in Joomla makes it hang at the "Authenticating, please wait..." screen, and the password of user "admin" is changed in eGroupware.
Anyhow, I wonder if anyone has gotten this working. Thanks!
