Thanks Amos, Kerberos is really hard to learn for a rookie like me, but you explained it in an excellent and concise way. In my case, the SQUID servers are joined to the domain with their respective SPN and UPN that I mentioned in the msktutil command. And in the case of the Load Balancer HAProxy

Thanks, Brett, for the answer. I did exactly the same thing and it's working for me now. I only have to decrypt how to see the client's IP in SQUID's logs. I will follow your instructions to try to achieve it. Best regards, Gabriel El jue., 23 de jul. de 2020 a la(s) 21:23, Brett Lymn (

Hi Gabriel, same problem here on our HA systems. I think, this is caused by kerberos overall, the tickets are always bound to the hosts realname and address, look at "klist" on your client, and only exactly this name could be used as proxy entry. But if anyone knows a solution, i will spread
