Been wanting to get SSO working on the site for awhile to work with the Invoicing, Bugzilla and BackupPC systems. Joomla already has a database for accounts and the default security access of Joomla menus and pages are helpful - but how do I get Joomla to tell Apache once a user has authenticated?

Apache module mod_auth_tkt and a little unknown Joomla plugin called tktcookie hold the answer.

1&1 Cloud Servers are a good balance between a dedicated server and shared hosting. One of the best attractions to such a service is the ability to grow the spec of your server over time as your needs grow.

This is the situation I was in when I upgraded my server for an extra 1GB of Ram and 100GB disk. The CentOS images provided by 1&1 is not built on top of LVM and therefore cannot take advantage of being able to grow your partition without data loss and while the system is live - something that LVM provides.
