When run by a normal user, \fIlppasswd\fR will prompt for the old and new passwords. When run by the super-user, \fIlppasswd\fR can add new accounts (\fI-a username\fR), change existing accounts (\fIusername\fR), or delete accounts (\fI-x username\fR) in the digest password file. Digest usernames do not have to match local UNIX usernames. .SH OPTIONS \fIlppasswd\fR supports the following options: .TP 5 -g groupname .br Specifies a group other than the default system group. .SH SECURITY ISSUES By default, the \fIlppasswd\fR program is not installed to allow ordinary users to change their passwords. To enable this, the \fIlppasswd\fR command must be made setuid to root with the command: .br .nf chmod u+s lppasswd .fi .PP While every attempt has been made to make \fIlppasswd\fR secure against exploits that could grant super-user privileges to unprivileged users, paranoid system administrators may wish to use Basic authentication with accounts managed by PAM instead. .SH SEE ALSO \fIlp(1)\fR, \fIlpr(1)\fR, .br http://localhost:631/help .SH COPYRIGHT Copyright 2007-2009 by Apple Inc. .\" .\" End of "$Id: lppasswd.man 7600 2008-05-20 21:06:23Z mike $". .\"
