I can avoid it... As I told Douglas, I have control over server and client 
code, so is up to me to decide what I want... The lead developer idea was to 
use the Microsoft implementation using the "WWW-Authenticate: Negotiate" tag, 
but it's more likely that I'll use the Mozilla implementation (using GSS-
Negotiate in the tag and pure GSS code encoded in base64) only and later change 
to SPNEGO, from what I readed in SPNEGO RFC and Microsoft Implementation, will 
be simple...

There's (besides kx509) any implementation of this? Just to know, what issues??
