	Not sure what you mean by this. Do you mean include the
	HttpServletRequestWrapper class with the jCIFS package?

	Actually I did change the attribute name to NtlmHttpAuth
	and I put the NtlmPasswordAuthentication object in the
	session instead of "1". I realize this was the sort of thing
	that got me in trouble the last time but take a look. I think
	you'll agree it should work just fine. Pre-2.3 users can
	retrive that. It now implements java.security.Principal so I
	need to put that in the session so I can pass it to the
	NtlmHttpServletRequest (a.k.a your NtlmRequest). Doing
	this avoids performing NTLM SSP with each and every
	request which is noticably slower and provides the
	getRemoteUser functionality at the same time.

	Then we should change it to jcifs.http.ntlmdomain and
	jcifs.http.ntlmuser. It would also be nice to extract the
	workgroup and netbios hostname like I was doing
