Hello list. I was curious about disabling user accounts. On every other *nix system I administer, I use pw to set the lock attribute, or on systems without pw, I add a * to the user password field. Obviously, vipw doesn't really apply to Mac OS X, as user accounts aren't kept in the /etc/master.passwd file. For the record, I'm running Mac OS X 10.4.1. (Just upgraded from 10.3.9 last night). Thanks! ________________________________________________ Eric F Crist "I am so smart, S.M.R.T!" Secure Computing Networks -Homer J Simpson
