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,

       (-x username) in the digest password file. Digest usernames do not have to  match  local  UNIX  user-names. usernames.

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:
       chmod u+s lppasswd

       While every attempt has been made to make lppasswd secure against exploits that  could  grant  super-user superuser
       user privileges to unprivileged users, paranoid system administrators may wish to use Basic authenti-cation authentication
