Authenication problems

[Vadim <kutsyy@gmail.com>]

I updated my box today morning (I am using testing), and I lost my
authenications.  Seems like PAm is not using shadow passwords.  My
common-password contains only one live (default):

password        required        pam_unix.so     nullok obscure min=4 max=8 md5


Are there any other parameters which could contribute to this?

Thanks you,
