1. NAME▲

lppasswd - add, change, or delete digest passwords.

2. SYNOPSIS ▲

lppasswd [ username]

lppasswd -a [ -g groupname] username

lppasswd -x username

3. DESCRIPTION ▲

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.

4. OPTIONS ▲

lppasswd supports the following options:

  • -g groupname
         
    Specifies a group other than the default system group.

5. SECURITY ISSUES ▲

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:

 
Sélectionnez
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.
