Why does Kerberos authentication fail using the Smoothwall Proxy Pac?

Article #: Product Castle
1757 All All


When using Kerberos authentication, clients using the proxy need to reference the proxy by hostname, not by IP address


Kerberos authentication fails when using Smoothwall-generated proxy.pac files


The proxy.pac file that is generated on the Smoothwall will auto-generate depending on the way it was requested.

http://<Smoothwall_IP_address>/proxy.pac will have the IP in the proxy statement.

http://smoothwall.yourdomain.local/proxy.pac will have the FQDN in the proxy statement.

Setting clients to use: http://smoothwall.yourdomainlocal/proxy.pac as the configuration script should fix this issue.
