[sudo-users] sudo password issue with Winbind

[Kanthasamy, Murugesan]

Hi, I read this issue sometime back, but forgot what the cause was.. 

I have Linux hosts authenticating AD. When a AD user does sudo and types
a incorrect password, sudo doesn't ask for password second time, instead
it tries the same password(presumably) another couple times and exits.

[user at hostname ~]$ sudo su -
Password:
Sorry, try again.
Sorry, try again.
Sorry, try again.
sudo: 3 incorrect password attempts
