-/* This program can get or set NT printer security permissions from the
- command line. Usage: psec getsec|setsec printername. You must have
- write access to the ntdrivers.tdb file to set permissions and read
- access to get permissions.
-
- For this program to compile using the supplied Makefile.psec, Samba
- must be configured with the --srcdir option
-
- For getsec, output like the following is sent to standard output:
-
- S-1-5-21-1067277791-1719175008-3000797951-500
-
- 1 9 0x10000000 S-1-5-21-1067277791-1719175008-3000797951-501

-
- The first two lines describe the owner user and owner group of the printer.
- If either of these lines are blank then the respective owner property is
- not set. The remaining lines list the printer permissions or ACE entries,
- one per line. Each column describes a different property of the ACE:
-
- Column Description
- -------------------------------------------------------------------
- 1 ACE type (allow/deny etc) defined in rpc_secdes.h
- 2 ACE flags defined in rpc_secdes.h
- 3 ACE mask - printer ACE masks are defined in rpc_spoolss.h
- 4 SID the ACE applies to
-
- The above example describes the following permissions in order:
-
- - The guest user has No Access to the printer
- - The domain administrator has Full Access
- - Domain Users can Manage Documents
- - Everyone has Print access
-
- The setsec command takes the output format but sets the security descriptor
- appropriately. */
