Hi,

I'm trying to use Kibana on a server _A_ to access elasticsearch on a  
server _B_. elasticsearch is protected with a basic auth authentication on  
server B.

Kibana is also protected with basic authentication (and the same password)  
on server A.

I'm using this configuration  
[https://gist.github.com/hlassiege/179866de70c3d8d992ab](https://gist.github.com/hlassiege/179866de70c3d8d992ab) (inspired from here  
[https://github.com/johnhamelink/ansible-kibana/blob/master/templates/nginx.conf.j2](https://github.com/johnhamelink/ansible-kibana/blob/master/templates/nginx.conf.j2)  
)

I'm just trying the redirection by typing the following address :  
[http://A.com/es/\_search](http://A.com/es/_search) [http://a.com/es/\_search](http://a.com/es/_search) and I get a error 500. In  
the log I have :

2014/06/01 16:45:55 [error] 3721#0: \*1 rewrite or internal redirection  
cycle while internally redirecting to "/es/\_search", client: 192.168.50.1,  
server: [A.com](http://A.com), request: "GET /es/\_search HTTP/1.1", host: "[A.com](http://A.com)"

Any idea what could be wrong ?

Regards,

Hugo
