At the heart of Refinery's user management is the authentication plugin located in
What this really is is just a standard authlogic install extended with a few extra features like "I forgot my password" and hooked directly into the heart of Refinery's plugin system.
Authlogic allows you to easily integrate with other systems too. So you could be logged in into another system using authlogic and easily stay logged in between the two systems without having to login twice.
Adding New Users
New users can be easily added by going to the 'Users' area admin and clicking on "Add new user".
Limiting and Granting Access
Each user has a set of plugins they're allowed to see. You can control which plugins each user can see by checking and unchecking the checkboxes next to the plugin name when editing or adding a new user.
