[squid-users] problem with auth_ntlm and javascript

Hi everyone,

We have a problem with firefox, auth_ntlm and javascript. Our squid
server autenticate with AD through ntlm for Single Sign On. There is
no problem when we use IE, but when we use Firefox and the web page
requires Javascript, the client asks for the user/password for each
javascript component that the web page uses. If we disable Javascript
in firefox, works ok.

We know that it's not a squid problem, but I was wondering if someone
had the same problem.
