Hi,

I'm sorry, but I don't know the answers to your questions about juggling
the /etc/passwd file.  My superficial answer would be that when you
logon to the PC, that's who you are, unless you use the ntreskit su.exe.
The /etc/passwd file only provides a unix-like image of the PC's
authentication info for unix tools to use.

I believe the string in the GECOS field is an NT SID.

Regards,
Doug Wyatt
