Subject: Making 'su' work under a cygwin bash shell

I have had only moderate success getting su.exe from the Windows 2000
Resource Kit working as a drop-in for the unix 'su' command.
The version of su.exe that I am using is one that is not yet publicly
available, but the issues still remain (I had to get the newer version to
fix another issue I was having).

I don't know true shell scripting, so I wrote a simple perl script instead.
Assume the variables are defined correctly.
************************************************************
$ cat su2.pl
$user = 'Administrator';
$password = '********';
$domain = 'LocalHost';
$cygrootNT = 'C:\\cygwin';
$supathCYG = '/cygdrive/c/Program Files/Resource Kit';
open(PASSTMP,">/tmp/$user.password");
print PASSTMP $password;
close(PASSTMP);
print "\nAttemtping to execute the following:\n";
print "\"$supathCYG\\su.exe\" $user \"$cygrootNT\\bin\\bash.exe\" $domain -v
-e < \"$cygrootNT\\tmp\\$user.password\"\n";
system("\"$supathCYG\\su.exe\" $user \"$cygrootNT\\bin\\bash.exe\" $domain
-v -e < \"$cygrootNT\\tmp\\$user.password\"");
open(PASSTMP);
close(PASSTMP);
exit;
************************************************************

The script ~almost~ works as desired.  It runs the resultant bash prompt in
a new window.  I want to figure out how to make the new bash shell run
inside the bash shell it was run from.
Here is the output from when I run it:
************************************************************
$ perl su2.pl
Attempting to execute the following:
"/cygdrive/c/Program Files/Resource Kit\su.exe" Administrator
"C:\cygwin\bin\bash.exe" THIN-LINE -v -e <
"C:\cygwin\tmp\Administrator.password"
User=Administrator
Domain=LocalHost
ReferencedDomain=LocalHost
CommandLine=C:\cygwin\bin\bash.exe
TextualSid=S-1-5-21-1960408961-152049171-1060284298-500
LogonSid=S-1-5-5-0-7029156
CurrentWinsta+Desktop=WinSta0\Default
TargetWinsta+Desktop=WinSta0\Default
************************************************************

If anyone can tell me how to keep the shell in the same window, I'd be
appreciative.  Or if anyone knows of some version of su that works natively
under a cygwin bash shell, I'd be even more appreciative!

Thank you!
