PAM error

I am not able to authenticate.  I keep getting the below erro:
pam_vas*: pam_vas_is_vas_user: no PAM stack account info for user , looking up

The user name is not being passed.  It is just blank

here is the pam file:
auth     sufficient     pam_vas3.so debug
auth     required       pam_unix_auth.so try_first_pass debug
account  sufficient     pam_vas3.so debug
account  required       pam_unix_auth.so
password required       pam_vas3.so


Does this look right?

Here is what I am trying to do.
