Hello Jay,

I am having a similar issue using ES 1.4.3 + Shield 1.1. As soon as my 
application instance (with embedded ES node.client) starts up, it throws :

*Caused by: org.elasticsearch.shield.authz.AuthorizationException: action 
[indices:admin/exists] is unauthorized for user [__es_system_user]*

and therefore my application will not start. I have tried the following as 
per the documentation here 
(https://www.elastic.co/guide/en/shield/current/authentication.html#anonymous-access)
 
:



*shield.authc:           anonymous:                 roles: admin*

and




*shield.authc:        anonymous:                username: 
__es_system_user                roles: admin*

but they don't have any affect.

If there is any documentation I can read of the restriction(s) in 
ES/Shield, please can you point me to it ? I need to understand if this is 
something we can program/config around or whether we can patch Shield 1.1 
(we only support v1.1 until next release of our application).


Thanks,

Steve.
