lppasswd - add, change, or delete digest passwords.
lppasswd [ username ]
lppasswd -a [ -g groupname ] username
lppasswd -x username
lppasswd adds, changes, or deletes passwords in the CUPS digest
password file, passwd.md5. When run by a normal user, lppasswd will
prompt for the old and new passwords. When run by the super-user,
lppasswd can add new accounts (-a username), change existing accounts
(username), or delete accounts (-x username) in the digest password
file. Digest usernames do not have to match local UNIX usernames.
lppasswd supports the following options:
Specifies a group other than the default system group.
By default, the lppasswd program is not installed to allow ordinary
users to change their passwords. To enable this, the lppasswd command
must be made setuid to root with the command:
chmod u+s lppasswd
While every attempt has been made to make lppasswd 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.
