The biggest problem with this is, that there are no tools to fix or verify db files. If the /etc/pwd.db or /etc/spwd.db becomes damaged, you're screwed. Also, there are locking issue with in place updates of db files. Do the pw routines in libc even do locking? I don't think so. What happens if someone calls getpwnam() at the while someone else is writing a new entry into the database? Bang, you're dead. > -- > Dave Chapeskie, DDM Consulting > E-Mail: dchapes@golden.net Tom
