Hi, If I understand correctly, you've created a account for all squid and one for balance service, and you've associated the SPN of balance service for all squid account. Is this correct? Aren't there problems with ducplicat SPN in AD? A lot of thanks. -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/kerberos-auth-failing-behind-a-load-balancer-tp4658773p4660189.html Sent from the Squid - Users mailing list archive at Nabble.com.
