Description Anders Kaseorg 2010-08-13 04:47:50 MDT

On Ubuntu maverick, installing the winbind package configures an additional PAM module pam_winbind to run after pam_unix.  Then, I have to hit Ctrl+C twice to get out of the sudo password prompt:

$ sudo true
[sudo] password for anders: ^C
[sudo] password for anders: ^C
$

I've attached a patch that should do the trick.

Fixed in sudo 1.7.4p3, available now.
