+ <listitem><para><emphasis role="bold">auth</emphasis> is a special
+ scheme which ignores any provided ID and instead uses the current
user,
+ credentials, and scheme. Any ID (whether, 'user' like with SASL
+ authentication or 'user:password' like with DIGEST authentication)
provided is ignored
+ by the ZooKeeper server when persisting the ACL. However, the ID
must be
+ provided in the ACL because the ACL must match the form
'scheme:id:perms'.
+ This scheme is provided as a convenience as it is a common
use-case for
+ a client to create a znode and then restrict access to that znode
to only that client.

perhaps "only that user" would be clearer?
> Clarify documentation around "auth" ACL scheme
> ----------------------------------------------
>
> Key: ZOOKEEPER-2709
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2709
> Project: ZooKeeper
> Issue Type: Task
> Components: documentation
> Reporter: Josh Elser
> Priority: Minor
>
> We recently found up in HBASE-17717 that we were incorrectly setting an ACL
> on our "sensitive" znodes after the output of {{getACL}} on these nodes
> didn't match what was expected.
> In referencing the documentation about how the {{auth}} ACL scheme was
> supposed to work, it was unclear if it was a ZooKeeper bug or an HBase bug.
> After reading some ZooKeeper code, we found that it was an HBase bug, but it
> would be nice to clarify the docs around this ACL scheme.
