It's not intended for local accounts anyway. It's not just -c that adds the 1: mkpasswd.exe -d $USERDOMAIN -u $USERNAME also gives a uid that is RID+1. The ntsec page mentions using mkpasswd and mkgroup but does not explain how the uid or gid is chosen. I think my comment was prompted by the mention of numbers of 4 digits earlier in this thread. Having a 6-digit RID for my domain account I can see that the uid generation does straightforward arithmetic and not some sort of string processing. (Is it really 19106 this year? Some people wrote code that thinks so.) -- Owen Rees Hewlett Packard Laboratories, Bristol, UK -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/

HTH,

Actually, I meant how do I do it so that I don't have to edit
/etc/{passwd,group} manually
each time I add a user to XP? Is there a way to specify the mapping to
uid/gid numbers so that I get the
same passwd file automatically?
If not, I guess I could write a script.
Thanks,
Steve

I'm confused: a mapping from what to what? The SIDs will be different on
every Windows machine -- Windows assigns them, and Cygwin has not control
over that. If you simply want to say I'd like to add a user with a given
numeric UID, there is currently no way of doing this on Cygwin.
Besides, the default mapping is to take the last 4 digits of the SID for
the UID for local users, and 1 + the last 4 digits of the SID for
domain users, so every time you regenerate your /etc/passwd with
/bin/mkpasswd, your custom UIDs will be lost. There's no way to specify a
custom SID to UID mapping, though it may be possible to patch mkpasswd
(and mkgroup) to have such an option...
