Hello, I have set up a squid Proxy that uses samba/ntlm/krb5 to do SSO AD authentication in the Company. This works fine. My problem is that external Websites on the Internet that use NTLM authentication of their own do not work. My users enter their Details (DOMAIN\user and Password) and receive authentication failures Messages. Interestingly enough, this (almost) only occurs in Internet Explorer. The same sites work fine with Firefox. Thank you in advance for your much needed help. -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/Problems-with-NTLM-authentication-tp4667742.html Sent from the Squid - Users mailing list archive at Nabble.com. _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
