Loading Secured XSD SChema Files

> Hi Orbeons,
>
> I'm using the latest Orbeon Forms nightly build in an "seperate deployment".
> My own web app which contains the XForms requires authentication, which
> means the user first has to log in before using it.
>
> The security is implemented in a servlet filter, which checks for a valid
> credential in the users session. If a valid credential is present, simply
> the next servlet filter is called in the chain. If no valid credential is
> available, the user is forwarded to a login page - to obtain a new, valid
> credential.
>
> Now my problem is that I can't reference any XSD schema in my XForms page
> like <xforms:model schema="schema.xsd">. When I do so, I get the following
> error page from Orbeon Forms:
