Definicja login module

Java class defined by the Java Authentication and Authorization Service (JAAS) that defines the authentication logic for a particular authentication mechanism. For example, the Basic Authentication login module requires that the user logs on with user ID and password.

Login modules are plugged into the authentication framework of the J2EE Engine to provide particular types of authentication. Login modules can be grouped in login module stacks which are then assigned to applications and components in the J2EE Engine.
