-----------------------------------
Fix Version/s: (was: 3.5.3)
> A new feature proposal to ZooKeeper: authentication enforcement

> Key: ZOOKEEPER-1634

> Up to the version of 3.4.5, ZooKeeperServer doesn't force the authentication
> if the client doesn't give any auth-info through ZooKeeper#addAuthInfo method
> invocation. Hence, every znode should have at least one ACL assigned
> otherwise any unauthenticated client can do anything on it.
> The current authentication/authorization mechanism of ZooKeeper described
> above has several points at issue:
> 1. At security standpoint, a maleficent client can access a znode which
> doesn't have any proper authorization access control set.
> 2. At runtime performance standpoint, authorization for every znode to every
> operation is unnecessarily but always evaluated against the client who
> bypassed the authentication phase.
> In other words, the current mechanism doesn't address a certain requirement
> at below:
> "We want to protect a ZK server by enforcing a simple authentication to every
> client no matter which znode it is trying to access. Every connection (or
> operation) from the client won't be established but rejected if it doesn't
> come with a valid authentication information. As we don't have any other
> distinction between znodes in term of authorization, we don't want any ACLs
> on any znode."
> To address the issues mentioned above, we propose a feature called
> "authentication enforcement" to the ZK source. The idea is roughly but
> clearly described in a form of patch in the attached file
> (zookeeper_3.4.5_patch_for_authentication_enforcement.patch): which makes
> ZooKeeperServer enforce the authentication with the given 2 configurations:
> authenticationEnforced (boolean) and enforcedAuthenticationScheme (string)
> against every operation coming through ZooKeeperServer#processPacket method
> except for OpCode.auth operation. The repository base of the patch is
> "http://svn.apache.org/repos/asf/zookeeper/tags/release-3.4.5/";
