[jcifs] Re: NTLM HTTP Filter Does Not Work With SMB Signing

Using the domain controller parameter in the filter didn't seem to have an
effect, both when I put in a real IP and when I put in a client IP. When I
tried to run the ListFiles example, it kept giving me an error that the user
has been blocked, or something to that effect, with the same message whether
I had the *jcifs.smb.client.signingPreferred* as true or false. I'll keep
messing with it, since for whatever reason, I can't even get it to fully
authenticate me at this point, let a lone a remote client. A big thanks to
you all for helping as much as you have.
