If you have multiple WordPress installations using the same database, this plugin makes it possible for one installation to run off the user table of another installation. Main user table selection is completely configurable through the options panel, and permissions of the users can be different from blog to blog.

When you switch the user table from one blog to another, all level 10 users (administrators) of the blog you are switching to are also made level 10 users on the blog in which you installed the plugin. Only a level 10 user can make the switch.

After you switch, you should visit the Users section of the Admin panel to setup permissions for all other users. They will be listed as "No role for this blog" in WordPress 2.3, or with an empty Role column under "All Users" in WordPress 2.5/2.6.

Note that ideally the blog you are switching should not have more than the default admin user. Content created by all other users will automatically be assigned to more or less random users from the main blog when you switch (based on user_id). Future versions of the plugin may support migrating existing users and content.
