i know this Articles and a lot more from the Web. Mostly all do the same. The Option "--enable-auth="ntlm,basic"" doesnt exists anymore in the 3.3.5 Release of Squid. Try to use --enable-auth to get most of the Auth Helpers. But i dont understand why it works on the other Machine and on my new one it doesnt. As i said all the Samba,Winbind, Kerberos installations and tests are working all with success. But when i try to use the new Server Proxy with Port 3128 (without Dansguardian) i get all the Time the Authentification Window. I changed the user/group for the winbindd_privilegde. Everything starting and running but the Auth doesnt work :( and dont know where is the Problem. As said i did this like tons of Webpages wrote. But this Machine dont like me.
