Chaining Windows Active Directory with Default Auth

[rdifrango]

I am attempting to configured Chaining Windows Active Directory with Default Auth.  I was able to successfully configure LDAP Auth against my Actvice Directory store without the chaining.

I have attempted some other config changes based upon the following post:

But when I do so I get the following:

Is LDAP chaining working at all? Anyone got it working?

I got my basic LDAP authentication working. But once I chained LDAP with Default Auth I got this exception:
