My environment is Active Direcory Single Forest Multidomain with each domain having multiple domain controllers. Make sure the reverse DNS lookup of the proxy matches the expected service name. This is one of the more common sources to confusion. Also make sure you specify the right keytab to squid_kerb_auth and that it's readable by your cache_effective_user. Regards Henrik
