Hi BitByter,

Yes, I think your analysis is correct. I am looking at our code and I
don't see us passing the authentication information when we load the
schema. Would it be possible for you to create a small war file that
we can use to reproduce this problem? Otherwise of course a workaround
is to setup your filter so authentication is not required to access
*.xsd files.
