>Description:
When logging into my FreeBSD server, I logged on as my regular user and typed the password correctly but added a few extra characters after I entered my password. Suprisingly, the machine let me in. I tried to log in with a completely wrong password and it denied access. This problem also occurs when su'ing to root. I type su, then type the password (correctly) and add extra characters on the end and it granted me root access.
>How-To-Repeat:
Log in using an account, type the correct password and a few extra characters after the correct password and try to log in. You will be validated and access is granted.
