Hi, everybody.
I need help from somebody experienced in C programming for
Novell.
My question is:

? I need to change an user trustier rights from his account
? when he exiting to DOS prompt from the application running
? at this account. Then, when he going back to the application
? I need to change the rights as they were initially setted.

Description:
I am writing an security system for my FoxPro/LAN application.
This application will be accessible from only one artificial
multiuser account. In order to run the application I have to
give to the users all the rights (except create/delete files)
for the directories where databases are kept. However, I must not
provide any access to those databases other than within my
application. It is not a problem to logging an user out when
exiting the application but I was asked to provide access to the
DOS prompt. The only way I could see to hide databases directories
from an user at the DOS prompt level, is to change his trustier
rights while exiting (not logging out from account) the
application. Novell's people said that it is possible to wright
rights server program and then make call to it from the
application. However, I have no idea what the right server is.
Is it must be an NLM or TSR and ..........
I have C kit for FoxPro and great desire to wright (or find
somewhere) such a program. It must be a C code.
Any help will be greatly appreciated.
