  The terse file security dept 
 The Question is:
 
how to grant permission for a user so that he can access the files in a
 directory ?
 
 
 The Answer is:
 
  Via an ACL and identifiers (both default and "normal" on the parent
  directory, and "normal" on all existing file versions), via subsystem
  identifier on an executable image and ACL entries on the target file
  (and potentially directory), an executable image installed with privileges,
  or via matching the user's UIC group or membership values and the fields
  in the object protection masks for the target file(s) and directory.
 
  Details are available in the OpenVMS Security Manual.
