This paper discusses file system Access Control Lists as implemented in several UNIX-like operating systems. After recapitulating the concepts of these Access Control Lists that never formally became a POSIX standard, we focus on the different aspects of implementation and use on Linux.

Presented at the USENIX Annual Technical Conference, San Antonio, Texas, June 2003.
