If someone asked me to invent the most unintuitive, obfuscated interface possible for setting up cifs.ko authentication, I'd be hard-pressed to improve on SecurityFlags. Personally, I'd like to see that go the way of the dodo. We ought to have a sane, fixed heuristic that decides what authentication to use based on the NEGOTIATE_PROTOCOL exchange with the server. Then, we could just allow people to override that by setting a sec= mount option. -- Jeff Layton <jlayton@xxxxxxxxxx> -- To unsubscribe from this list: send the line "unsubscribe linux-cifs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
