It bcoz you enable two authentication mechanism, Ntlm as well basic.... disable one and it will not prompt two time :-) -----Original Message----- From: Benedikt Brandt [mailto:forum@xxxxxxxxxxx] Sent: Saturday, March 27, 2010 5:21 PM To: squid-users@xxxxxxxxxxxxxxx Subject: Two Login Windows Hello alltogether I am running Squid 2.7 Stable on a Debian Lenny system. The Squidusers authenticate against an ADS-Server and everything works fine, as long as the user connects from a computer within the Domain. When using the Proxy from a computer outside the Domain a Login Window appears, as it is supposed to. However this Login Window doesn't work. It just says: The proxy 192.168.3.101:3128 is requesting a username and password. The site says: "" After giving the correct login-information, this window just pops up again and again and again. However after cancelling this window, a second window appears saying: The proxy 192.168.3.101:3128 is requesting a username and password. The site says: "Squid proxy-caching web server" Entering the login-information in this window works. The user isn`t queried again and has access to the internet. Why is this first useless login window showing up? Is there any way to suppress it? Or have I misconfigured something? My squid.conf is attached. Thanks in advance. Hopefully I am not violating some rules right now. Since this is my first post on a mailinglist, I am simply missing the experience.
