Flavio Junqueira commented on ZOOKEEPER-1525:
---------------------------------------------

+1, thanks for that patch, [~randgalt]. I have merged to master, but the merge 
to 3.5 failed. The fix version in the jira says 3.5.3, so if this needs to go 
to 3.5.3, I'll need a patch for that branch. If not, then let me know and I'll 
close this issue.

> I want to plumb the ZooKeeperServer object into the auth plugins so that I 
> can store authentication data in zookeeper itself. With access to the 
> ZooKeeperServer object, I also have access to the ZKDatabase and can look up 
> entries in the local copy of the zookeeper data.
> In order to implement this, I make sure that a ZooKeeperServer instance is 
> passed in to the ProviderRegistry.initialize() method. Then initialize() will 
> try to find a constructor for the AuthenticationProvider that takes a 
> ZooKeeperServer instance. If the constructor is found, it will be used. 
> Otherwise, initialize() will look for a constructor that takes no arguments 
> and use that instead.
