different file access permissions from within a DELPHI app

Hi ,

how can I use different file access permissions from within a DELPHI
application than the user really has? I want to write/delete files inside a
LAN directory from a DELPHI app where the user has only read rights in the
directory. Thanks for your help!

You can't. The only solution is to start the application as a different
user.

No, that's not true. Ever heard of the NT4-commands "SU" and "RUN AS"?

With RUN AS and SU you start the application as a different user (which I
said he had to do) !

But you do SU from within the users account. Your solution seemed to be to
logout and relogin with the new account. So what....

Re:different file access permissions from within a DELPHI app

Something to think really-hard-about will be ... if you enable your
program to do super-magical things, then anyone who can get access to your
super-magical program will be able to do them. That concerns me.

Being able to do something programatically, that you are authorized to do,
is convenience.

Being able to do more than you could ordinarily do, is a security risk.
Particularly if the system administrators are not very conscious of your
program's capabilities.

Re:different file access permissions from within a DELPHI app

Perhaps the user could place a record with the delete or addition request into a
database file in a public directory.

A application running with full privileges would monitor this file and if the
user's request meet all of the requirements (User name, requested item to delete
or add, etc.) this application would delete the users entry from the file and
make the requested deletion or addition to the protected file.

This way the user never has direct write/delete access to the protected database
and it is easy to log the actions.
