This however not only limits the encryption types of session keys but all tickets as well and applies to the whole machine not just the NFSv4 service. This has a needlessly high security impact on both machines. Could this go in an appdefaults clause instead? My guess is not. I remember having to add allow_weak_crypto to libdefaults instead of appdefaults. But I thought I'd ask. If not, a command line argument to gssd seems reasonable. -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
