For two users with the same UID, give one an unused UID (edit /etc/master.passwd for this), and change their GID if necessary. Rebuild the password database. Then, change the ownership of all of their files to the new UID (or just chown username:usergroup) Unless these users change files all over the system, they should basically have a home directory, mailbox, and probably some temp files. chown -R usergroup:username /home/username /var/mail/username ...usually does the trick on most systems. Be careful with chown -R--it recursively spans subdirectories. Nothing like having a whole filesystem owned by one of your users ;-) > Thanks. > > gf. > > > > To Unsubscribe: send mail to majordomo@FreeBSD.org > with "unsubscribe freebsd-questions" in the body of the message > -- Ryan Thompson <ryan@sasknow.com> Network Administrator, Accounts SaskNow Technologies - http://www.sasknow.com #106-380 3120 8th St E - Saskatoon, SK - S7H 0W2 Tel: 306-664-3600 Fax: 306-664-1161 Saskatoon Toll-Free: 877-727-5669 (877-SASKNOW) North America To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
