About this eBook
Halt. Identify yourself.
The PAM mechanism is used only for authenticating a user. Apart from authentication, i.e. checking if the user can work, the operating system must also know information about a given user. This information is referred to as user authentication. The micro-course describes the methods of identification with the use of the NSS mechanism which is the default method in the Linux system.
