Mapping of ADFS permissions to Linux permissions

------------------------------------------------



  ADFS permissions consist of the following:



	Owner read

	Owner write

	Other read

	Other write

	- Owner read

	- Owner write

	- Other read

	- Other write



  (In older versions, an 'execute' permission did exist, but this

  does not hold the same meaning as the Linux 'execute' permission

  and is now obsolete).



  The mapping is performed as follows:

  There is no restriction on what you can do with these masks.  You may
