How to organize access control in Yii?

Question

Yii

Hello! My users are stored in the following table:

CREATE TABLE IF NOT EXISTS `users` (
  `id` int(255) NOT NULL AUTO_INCREMENT,
  `nick` varchar(50) NOT NULL,
  `mail` varchar(255) NOT NULL,
  `fName` varchar(255) DEFAULT NULL,
  `mName` varchar(255) DEFAULT NULL,
  `lName` varchar(255) DEFAULT NULL,
  `salt` varchar(255) NOT NULL,
  `pwd` varchar(255) NOT NULL,
  `group` int(11) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

There are elementary groups (admin, buyer, client, manager).
How do I create groups, roles, operations, etc.?
I'm just starting to learn Yii.

There is no need to figure it out yourself yet, but people send RBAC to smoke.
