This module uses a password derived from the MD5 hash of the username and serial number. The serial number can be retrieved by an unauthenticated user at /info.xml. Attempts to change the user password via passwd or other tools have no effect."

Se presenta un m\u00f3dulo PAM personalizado para la autenticaci\u00f3n de usuarios que omite la autenticaci\u00f3n de usuarios tradicional. Este m\u00f3dulo usa una contrase\u00f1a derivada del hash MD5 del nombre de usuario y el n\u00famero de serie. El n\u00famero de serie puede ser recuperado por un usuario no autenticado en el archivo /info.xml. Los intentos de cambiar la contrase\u00f1a del usuario por medio de passwd u otras herramientas no tienen efecto"
