Title: User Security File Permissions for 3+Open Servers

On a 3+Open server with user-level security, file access problems
can stem from creating a child subdirectory under a parent
subdirectory and not copying the parent permissions to the child
directory.  This article explains how the file permissions are
assigned on 3+Open servers running user-level security.

Initially, when a server is first installed with 3+Open software,
the root drive of all partitions is provided with default
permissions.  The root directory (\) under that drive letter is
set up with "set explicit permissions."  After defining the
correct permissions, any subdirectory and file created under a
parent directory will have the same permissions as the parent if
that parent is set up with "set explicit permissions."  However,
"use default permissions" is enabled on the new subdirectory.
Any file or subdirectory that is created under a directory that
has default permissions will get assigned the permissions of the
root drive.

Here is a graphic representation of this explanation:

                         E:   default permissions are defined here
                         |
                         E:\   "set explicit permission" enabled
                         /        no one permitted
                        /
                   E:\tst  "set explicit permission" enabled
                   /     Admin:rx
                  /      Guest:rx
                 /
             E:\tst\tst1  "use default permission" enabled
                /     Admin:rx
               /      Guest:rx
             /
            /
       E:\tst\tst1\tst2  "set explicit permissions" enabled
                          no one permitted
