Title : SUPER.EXE: switch SUPERVISOR equivalence on/off
Keywords: SUPERVISOR EQUIVALENCE RIGHTS SECURITY UTILITY
SUPER.EXE allows to switch SV equivalence on/off when needed. Do
your daily work as normal user, and be SV only when needed. Includes
DOS and Windows version. No security gap, since you have to be SV
equivalence to initialize SUPER for you.

Program history / New Features
Aug 92: - Allow to run SUPER against another user's account.
Sep 92: - Allow to run BATCH files and internal DOS commands
- Output redirectable with DOS pipes
SUPER.EXE (Windows version)
The Windows versions displays the SUPER status of up to 8 servers at
a single glance. Nice icon, but limitations: not applicable to
other users & no commands executable with temp SV rights.
Background:
"SUPER -" will modify the security byte of your bindery property
SECURITY_EQUALS to 0x22 (read/write object). This allows the
user to change his/her own security equivalences.
Then the Supervisor equivalence is removed.
Since the user may change the equivalences now, he/she can later add
Supervisor equivalence with "SUPER +" when needed.
"SUPER <command>" will first add Supervisor equivalence, then
execute the command, and finally remove Supervisor equivalence.
SUPER allows a user who in Supervisor equivalent to do the daily work
as normal user, while Supervisor equivalence is available when needed.
This reduces the risk of accidental damage to files caused by
carelessness, unattended workstations, or viruses.
This program was written by Wolfgang Schreiber in Borland's Turbo Pascal.
Hints, Internals, Security and Warnings:
SECURITY.EXE brings a warning:
'Has incorrect access security on the SECURITY_EQUALS property'.
BINDFIX warns:
'Warning: Object <name> property SECURITY_EQUALS has incorrect
security flags.'
Basically, for each user there is a standard property in the bindery
associated with the user called SECURITY_EQUALS, which contains a
list of users and groups to which that user has security equivalence.
When a user is created, the rights to this property are Supervisor
Write (meaning that only a supervisor equivalent can grant or change
equivalences) and User Read (meaning that a user can read their own
equivalences). The supervisor also has the ability to change the
rights mask to this property.
This is what SUPER.EXE does ... it changes the rights mask for a
user (can only be done by somebody with supervisor equivalence) so
that the user then can add their own security equivalences.
"SUPER -" will modify the security byte of your bindery property
SECURITY_EQUALS to 0x22 (read/write object). This allows the user
to change his/her own security equivalences.
SUPER allows a user who is Supervisor equivalent to do the daily
work as normal user, while Supervisor equivalence is available when
needed. This reduces the risk of accidental damage to files caused
by carelessness, unattended workstations, or viruses.
SOLUTION
The warnings are expected and desired in combination with SUPER
since a supervisor should be informed about the existence of other
supervisors - even with modified security access flags.
If the users that were highlighted in SECURITY or BINDFIX did NOT
use SUPER there might be a severe security gap.
SUPER and WSUPER have parameters that allow resetting the bindery
flag to it's original state - obviously this will prevent these
users from receiving SV equivalence with SUPER.
