This plugin is for WordPress 2.6 or 2.7. It enables WordPress to generate cookies that work with bbPress 0.9 so that single sign-on can be accomplished between the two. Follow the usual integration instructions and enable this plugin in your WordPress installation. I also advise clearing your cookies.
The integration is all up and running on my site at BayAnime.com. I’d like to add that I was able to put the plugin together without writing a single line of code! It’s literally all the necessary functions cut and pasted directly from WordPress 2.5.1 pluggable.php, so kudos to WordPress for making it easy!
When you do cookie integration please keep in mind that there are some login hooks in pluggable that might not be called in either WP or bbPress depending on which side your user logged in from. This might affect the functionality of some plugins.
For example, after rerouting all my bbPress logins to WP I realized that the ‘bb_set_current_user’ action hook on a bbPress plugin I used was no longer being called, so I had to incorporate it in on the WP side using the ‘set_current_user’ hook.
bbPress 1.0 users should use this plugin instead.
