[jcifs] How to stop the network pop up login window?

There could be a couple of things going on here:
 
1) IE doesn't think that your web site is a member of the Local Intranet
zone.
If the site is not a member of the Local Intranet zone, you will get the
logon pop-up dialog instead of being logged in automatically.  Make sure
your web site is a member of the Local Intranet zone only.  It should
not be a member of the Trusted Sites zone.  Check the indicator at the
bottom of the screen to see what zone IE thinks the site is in.
(There is a known bug in IE, if you are relying on your proxy
configuration to define the zone for web sites.  (Tools->Internet
Options...->Security->Local intranet->Sites...->Include all sites that
bypass the proxy server)  For each new browser instance, IE doesn't
load/initialize your proxy configuration until after it initiates the
process of making the first HTTP request.  Therefore, the first HTTP
request of each new browser instance is ALWAYS made using the context of
the Internet zone, even though your proxy configuration settings may
indicate otherwise.  It does not go back and re-assess the security zone
to be used for the first HTTP request once the proxy configuration has
been loaded.  I fought Microsoft long and hard on this bug, but they
will likely never fix it.  The manual zone definitions are always
respected by IE, regardless of the browser's initialization state.)
 
2) The web site could be rejecting the credentials automatically
supplied by the browser.  If the browser automatically provides
credentials and the server returns a 401 error in response to the NTLM
type 3 message, the browser will prompt the user to manually enter
credentials and re-try NTLM with the manually entered credentials.  I
would suggest taking a packet capture to see if this is what is going
on; if your site is really a member of the Local Intranet zone.

Hello, 

Have any one run into this problem before, please advise me what I
should do to stop the network dialog pop-up prompt with the intergrated
authentication on MS Windows XP.

We implemented an application with SSO. It works fine excepted that
everytime I launch the IE browser to send a request to that application,
it keeps pop-up the network dialog login prompt even that I have added
the site in the intranet zone and set the custom level to "Automatic
logon only in the Intranet zone". I did alot of searching and most of
the documents that I found they all mention the same thing about adding
the site in the intranet zone and trusted site. Is there ANY thing else
that I should check to stop the pop-up dialog? 

MY client OS and the IE browser

XP Version 2002 w/SP-2


IE v6.0.2900.2180.xsp_sp2_gdr.050301-1519

Thanks very much!!
