-----------------------------
Hi ,
I have setup 3 apache-nifi node along with one zookeeper. I have integrated
LDAP for the authorization. When I am deploying nifi cluster on 1 single node,
I am able to login on the UI.
But , on multiple node in the apache-nifi cluster, on login on the UI , I am
getting "Unable to validate the access token. " error.
Can you please tell us the reason.
Thanks

> Components: Security
> Affects Versions: 1.10.0
> Reporter: Pradeep
> Priority: Major
>
> *Scenario :* A cluster has been setup using the three node of the nifi. LDAP
> has been been configured. The token has been generated and used to access the
> api. In addition, the load balancer has been integrated with cluster with
> round-robin algorithm.
> *Problem :* While reusing the token with subsequent api call, it get failed.
> Due to invalid token.
> *Observation :* The load balancer using the round-robin algorithm where the
> subsequent call has been forwarded the other nifi node in the cluster. Hence,
> the token valid in the one nifi node is not valid to other node in the
> cluster.
> *Logs : _"_*_Unable to validate the access token."_
