[Bug 998437] [NEW] Can't log in on a tty

[Andreas Raster]

Public bug reported:

I have upgraded from 11.10 to 12.04 and just noticed that I can not log
in on a tty. I can enter my username and when I press enter it waits for
a moment and then goes straight back to the username prompt without ever
asking for my password.

Looking in /var/log/auth.log it seems this is caused by some kind of permissions problem:
May 12 15:13:16 capcom getty[2774]: checkname: Operation not permitted

My groups:
~> groups rakete
rakete : rakete adm dialout cdrom audio video plugdev lpadmin admin sambashare

and:
~> ls /dev/tty* -la
crw-rw-rw- 1 root tty     5,  0 May 12 15:11 /dev/tty
crw--w---- 1 root tty     4,  0 May 12 15:11 /dev/tty0
crw-rw---- 1 root tty     4,  1 May 12 15:13 /dev/tty1
crw--w---- 1 root tty     4, 10 May 12 15:11 /dev/tty10
crw--w---- 1 root tty     4, 11 May 12 15:11 /dev/tty11
crw--w---- 1 root tty     4, 12 May 12 15:11 /dev/tty12
crw--w---- 1 root tty     4, 13 May 12 15:11 /dev/tty13
crw--w---- 1 root tty     4, 14 May 12 15:11 /dev/tty14
crw--w---- 1 root tty     4, 15 May 12 15:11 /dev/tty15
crw--w---- 1 root tty     4, 16 May 12 15:11 /dev/tty16
[...]

Any suggestions how to fix this would be very welcome!
