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

Well I just answered my own question; the registry entries have nothing to
do with the authentication. As of right now, it is still allowing me to
authenticate transparantly, but whenever anyone else attempts to do a log
on, whether I have previously logged on or just restarted with a freshly
downloaded .jar file, it still will not allow them to authenticate. It hangs
right where it was hanging for me, it'll pre-authenticate, but will not
authenticate the remote user. Any ideas or suggestions would be great.
