Suppose that the values for Owner and Group for a user named Carla are otto and otto_staff, respectively. The value for Other (call it otto_other) is everyone at Carla's company except for Carla and the members of otto_staff. Carla creates these required Default ACLs on her folder named Project1:
Default Owning User with permissions rwx (read, write, execute)
Default Owning Group with permissions rx (read, execute)
Default Other with permissions no-read, no-write, no-execute
Default Mask with permissions rw (read, write)
Any file or folder subsequently placed in the Project1 folder inherits these basic permissions from Project1:
The file or folder Owner value is otto and otto has read, write, and execute permission on that file or folder
The file or folder Group value is otto_staff and otto_staff has read and execute permission on that file or folder
The file or folder Other value is otto_other and otto_other has no-read, no-write, and no-execute permission on that file or folder
Also, the file or folder has a Mask entry in the Access Control List Permissions scrolling list with value rw (read, write).
If Carla also adds an optional ACL of type Default User (Default Group) for the Project1 folder, then any file or folder subsequently placed in Project1 will inherit an ACL of type User (Group).
