I am using the newest version of Ubuntu 12.04 Linux 3.2.0-29-generic #46-Ubuntu SMP Fri Jul 27 17:03:23 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

When I try to log into TTY# I get a login incorrect. But when I login to term with 'sudo -v' to validate it logs in just fine and on top of that I log into my machine fine as well. Below is my output of term.

supaiku@lightfleet:~$ sudo -v

The first attempt I pressed enter just to show that validation is working correctly, second attempt I logged in. Any suggestions would help. Thank you.
