Hello again, all!  I'm happy to see that the OS/2 newsgroups have been moving
along while I was away...  (Enough of that--here's my question:)

 I'm running EE 1.2 on a computer that is used by three people aside from 
myself, but I do the chores and make sure everything is running smoothly.
Is there any program (shareware pref.) which would divy the machine into
protected segments like UNIX?  (Where each user has his own directory such
as c:\root\lance and c:\root\JohnDoe, etc.)  I'd like to set it up much like
UNIX, but fancy things like making files world-readable aren't important.
I'd also like to keep any directory level BELOW the user's home directory
inaccessable to read, but executable--so that users wouldn't have access
to the operating system or device drivers.
 The OS/2 security system is nothing like that and doesn't do much out of the 
LAN or SQL environment...
 Also I'd like each user to have a password, of course.

TIA
