I think the part with NTLM negotiation for every page is normal for http
Once the browser has negotiated basic or ntlm for a page it continues to
use the the same method for all subsequent requests on that site.
I think you can avoid this with https. Then you have a reliable/trustable
the brwoser/server does not need auth for every request.

Ämne: [jcifs] Problem using JCIFs and JSF
I construct a web application and use JCIFs to authenticate. I observed in
the NtlmHttpFilter class, that filter negotiate with all pages.
Why? I think the authentication (the NTLM negotiation) is necessary only in
the first user page call.
My context is:
I create my own filter class, based in the NtlmHttpFilter, and I use JAAS to
connect to our internal authorization system.
In this system, we use a intranet web service to get the user credentials.
Because the NTLM authentication itself and this authorization step are a
expensive operations, I tryed to create a cached Subject (JAAS Subject), put
it in the session (http request session). Only the first call negotiate a
NTLM. At this moment my application works fine.
But when I use JSF (all .jsf request are intercepted by Faces Servlet), my
JSF file not receives the request parameters. The application negotiate
(NTLM), creates a Subject and put it in the session. After this moment, all
request parameters send to the JSF page are missing. I tryed to debuger but
I could not identify the problem.
If I remove this cache (negotiating all http requests) my JSF application
works fine again.
After make a revision over my code, and compare with the JCIFs http filter
implementation, I remember that JCFs do not use a cache. My question is why?
There are some requirement for that?
I use Tomcat 5.5.14, JSDK 1.4, JCIFs 1.2.7, and JSF 1.1.
Thanks in advance.
