"Security/2 is a multi-user system for OS/2. It provides controlled access to files, drives, drivers and other OS/2 stuff, based on access control list for each user. Security/2 has modular structure and can be easily (i hope ;)) extended and provides a API for developers to enable their applications be multi-user."
