Below is the recipe for getting this to work with Ubuntu with Ubuntu 12.04, Confluence  Confluence 5.1.1, Apache Apache, and modmellon.

I choose modmellon because it seemed like a cleaner solution than mod_shib, requiring no additional daemons and much simpler configuration.

Before you start, make sure you have these bits:

• A correctly configured apache web server that is able to serve an HTTPS web site (https://example.com).
• A SAML Identity Provider (IdP).
• An account on that IdP.
• An An attribute that can be used as username in Confluence (for example eduPersonPrincipalName). Attributes for full name and e-mail are optional but recommended. In this case we assume 'mail' and 'displayName' can be used.
• The user name of the to-be administrator account. So, if you choose eduPersonPrincipalName choose eduPersonPrincipalName as the attribute for username, you need to know your own value (for instance 'dvisser@surfnet.nl'.
