[Chameleon] changing authenticator

[JBaum at townofbethlehem.org]

I am trying to authenticate against a AS400 rather than my own database.  I
am trying to put code into Authenticator.php to open an ODBC connection to
the 400.  If successful, I consider the user authenticated.  I keep running
into problems - the sample_user.phtml just goes blank.  Has anyone modified
the authentication for their own purposes who would like to share code?
Thanks.

Here is what Ive got:
