lppasswd - add, change, or delete digest passwords.
-a [ -g
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:
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:
- -g groupname
- Specifies a group other than the default system group.
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.
