It's not intended for > local accounts anyway. It's not just -c that adds the 10000: mkpasswd.exe -d $USERDOMAIN -u $USERNAME also gives a uid that is RID+10000. 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/
