*** This bug is a security vulnerability ***

Public security bug reported:

users-admin ignores the setting in sudoers, where I have configured to
use the 'target-password' instead of insecure 'user-password'. Here the
line in 'sudoers:

Defaults       !lecture,tty_tickets,!fqdn,targetpw,timestamp_timeout = 0

This definitely is a severe security issue, because it is absolutely useless to 
ask a user a second time for his password to gain administrative rights (he 
already logged in with the same PW).
I set up a genguine root-account, so I can use a simple password to comfortably 
log-in as a user, while the root-account is protected by a strong password. 
This password should be used to gain administrative rights!
