A subdirectory is established in the directory. A sub-level subdirectory is established in the subdirectory having access permissions defined by a second owner. The subdirectory is publically accessible to anyone satisfying the access permission defined by the first owner, such that a change directory system call is executed for a user in the subdirectory, even though the user has not authenticated the access permission defined by the second owner.
