## Class TAuthManager

Description

TAuthManager class

TAuthManager performs user authentication and authorization for a Prado application. TAuthManager works together with a TUserManager module that can be specified via the UserManager property. If an authorization fails, TAuthManager will try to redirect the client browser to a login page that is specified via the LoginPage. To login or logout a user, call login or logout, respectively.

To load TAuthManager, configure it in application configuration as follows, <module id="auth" class="System.Security.TAuthManager" UserManager="users" LoginPage="login" /> <module id="users" class="System.Security.TUserManager" />
