Description:

sudo 1.8.5.p2-1 doesn't work correctly, even the password is correct, it still
says "password incorrect" and can't gain root privilege.

Additional info:
sudo 1.8.5.p2-1
If replace the config file in /etc/pam.d/sudo with /etc/pam.d/su,
sudo works again.

The audit log shows the following messages:
------
Jun 16 16:34:56 adam-vm sudo: PAM no modules loaded for `sudo' service
Jun 16 16:34:58 adam-vm sudo: PAM no modules loaded for `sudo' service
Jun 16 16:34:59 adam-vm sudo: PAM no modules loaded for `sudo' service
------

Steps to reproduce:
1) Update sudo to the given version.
2) Execute sudo -v command and enter the right password.

Sounds like you made changes to the sudo pam file that caused the breakage. The default pam file works fine.

No changes to sudo pam file, but /etc/pam.d/other seems not the full version,
the content is the same with the sudo pam file.
(two line about account).

Reinstalling pambase seems to repair the breakage.
