Thanks for the reply Chris. >From squid FAQ, noticed that NTLM is only supported in reverse proxy/accelerator mode. Some more info : http://www.cgisecurity.com/lib/ntlmhttp.shtml mentions that not all proxy honours NTLM, but some do. That is why my Netcaches are able to handle NTLM. My questions: 1) But it would be most strange that squid on version 2.4 could serve up the pop-up auth box while version 2.5 cannot. 2) Besides suggesting Basic authentication or Digest authentication for the web site, is there any workaround on squid side? This is because we are an ISP and have no control over the webserver concerned. Any help would be most appreciated. Thanks.
