[Pkg-shadow-devel] Bug#709884: /bin/login: Cannot login as or su to root on /dev/tty1.

[Jeroen N. Witmond]

Package: login
Version: 1:4.1.4.2+svn3283-2+squeeze1
Severity: important
File: /bin/login

To update from squeeze to wheezy I need to login as root without using
X, gdm, etc.  So I use Ctrl+Alt+F1 to go to tty1. 

However, attempts to login as root result in "Login incorrect" with
the following lines in /var/log/auth.log:

May 26 14:07:38 BlackBox login[3792]: pam_unix(login:auth):
authentication failure; logname=LOGIN uid=0 euid=0 tty=/dev/tty1
ruser= rhost= user=root 
May 26 14:07:41 BlackBox login[3792]: FAILED LOGIN (1) on '/dev/tty1'
FOR 'root', Authentication failure

Login in as a normal user followed by `su -` results in "su:
Authentication failure" with the following lines in /var/log/auth.log:

May 26 14:10:34 BlackBox su[3846]: pam_unix(su:auth): authentication
failure; logname=jeroen uid=1000 euid=0 tty=/dev/tty1 ruser=jeroen
rhost=  user=root
May 26 14:10:36 BlackBox su[3846]: pam_authenticate: Authentication
failure
May 26 14:10:36 BlackBox su[3846]: FAILED su for root by jeroen
May 26 14:10:36 BlackBox su[3846]: - /dev/tty1 jeroen:root

When I run a terminal window under X I can su to root.
