CDbAuthManager represents an authorization manager that stores authorization information in database.

The database connection is specified by connectionID. And the database schema should be as described in "framework/web/auth/*.sql". You may change the names of the three tables used to store the authorization data by setting itemTable, itemChildTable and assignmentTable.
