That should work provided you set the creds before any jcifs classes are
accessed. These are the default credentials so once you set them they
cannot be changed.

See the "Setting Client Properties" documentation for other methods to set
jcifs properties.

Huh? So you're using NtlmHttpURLConnection with the NtlmHttpFilter? You do
realize that the two features are separate? The NtlmHttpFilter is for
authenticating clients whereas the NtlmHttpURLConnection is the http

Mmm, it looks like NtlmHttpURLConnection expects request properties to be
'List's. Are you certain that is the correct way to set the cookie? Are
request properties not supposed to be List objects?
