Sense fails to authenticate users

[vicvega]

Our environment

Our elasticsearch (2.3.2) environment consists of

• a production cluster to keep and analyze data (secured by shield)
• a single node monitoring cluster (also secured by shield)

We have sense (2.0.0-beta5) installed on the single node monitoring cluster (kibana 4.5.0) and we use it to point the production cluster (using sense.defaultServerUrl).
On each cluster we have two realms for shield authentication: esusers (order 0) and ldap (order 1)

Step to reproduce

Create two local users (esusers) with same name (root) and different password on the production cluster and the monitoring cluster.
Connect to kibana on monitoring cluster using said local user (root).
Switch to sense.
It asks for credentials, but fails any authentication attempts for same username (root).

It seems to check credentials on ldap realm instead of esusers (which is first in order). See the following logs
