41 * Authentication of users in TYPO3
43 * This class is used to authenticate a login user.
44 * The class is used by both the frontend and backend. In both cases this class is a parent class to beuserauth and feuserauth
46 * See Inside TYPO3 for more information about the API of the class and internal variables.
