ADAM proxy bind redirection

I am working with AD LDS and have successfully setup a user using the
Proxy Bind Redirection with AD, based on the MSFT step-by-step guide.
We are working on an application that is in SharePoint. Users will
need to be authenticated against AD. Basically we will have users
setup in AD and will be authenticated using bind proxy in AD LDS. When
I try to authenticate / bind the user from LDP.exe the user is
authenticated sucessfully. But when we try it from the sharepoint
application the user is not authenticated. We are using Forms
Authentication. When i check the eventlog we see an entry "Membership
credential verification failed. ". Is there anything specific that
needs to be done to successfully authenticate the users?
userPrincipalName for the user is set. Our requirement is to use bind
proxy redirection where the proxy object is tied to the Active
Directory account through that account's security identifier (SID).

Did you find a solution ? I'm encountering the same problem.
