Default SMTPD SASL Auth Issues

Hi All,

I have done a lot of searching and can't seem to figure this out.

I have setup a mail server; components are as follows: Ubuntu 12.04 Server, Courier, MySQL, Amavisd-new, SpamAssassin, ClamAV, SASL, TLS, Postgrey and Roundcube

I can login to Courier and Roundcube.
I can send mail(including to external recipients).
I can recieve mail.

As far as I can tell everything is working, except for SMTPD authentication.

saslfinger -s output below:

Here are some relevant logs:

Any help would be appreciated as I have been at this for hours, and can't seem to work it out.
