The WordMine plugin for WordPress allows to integrate WordPress with Redmine. The plugin makes WordPress use Redmine session cookie for authentication (i.e., implements single sign-on with Redmine).
It is recommended to use this plugin along with the RedPress plugin for Redmine and the RedWord theme for WordPress. The RedPress plugin is required (otherwise you won’t be able to authenticate) while the RedWord theme is not.
