I came across an interesting overview of ntlm authentication possibilities at http://www.oaklandsoftware.com/papers/ntlm.html
I thought I'd just mention it here in case anyone who knows how nutch authentication works "under the hood" has anything to say about the listed options. The solution that's usually mentioned when talking about nutch and ntlm authentication is using a ntlm proxy, but it's basically just a make-do solution. I'm mostly interested in how the projects listed in the Oakland Software paper could be employed to do the job. Oh, and one more thing: is NTLM just a matter of porting it to java? As I understand it, samba implements the protocol in C, ntlmaps in python... ...anyway, enough of my ramblings... Cheers, t.n.a.
