> I've been investigating some sporadic and hard to reproduce test failures 
> related to authentication in cloud mode, and i *think* (but have not directly 
> verified) that the common cause is that after uses one of the 
> {{/admin/auth...}} handlers to update some setting, there is an inherient and 
> unpredictible delay (due to ZK watches) until every node in the cluster has 
> had a chance to (re)load the new configuration and initialize the various 
> security plugins with the new settings.
> Which means, if a test client does a POST to some node to add/change/remove 
> some authn/authz settings, and then immediately hits the exact same node (or 
> any other node) to test that the effects of those settings exist, there is no 
> garuntee that they will have taken affect yet.
