Hi, I have my system configuration with kerberos+ntlm+basic. All run perfect!!! but when a Firefox user pulse CTRL+F5 show a popup where the user have to put the username and password. When this user use IE o Chrome and pulse CTRL+F5 doesn't show the popup. The configuration Firefox change to: network.automatic-ntlm-auth.allow-proxies---> true network.automatic-ntlm-auth.trusted-uris---> domain.com I tried this: https://kb.bluecoat.com/index?page=content&id=KB4921&actp=RSS but it has not worked. Someone can help me remove the popup when you press CTRL+F5 from firefox?
