[jira] [Commented] (NIFI-7161) Issue with token replication in the cluster.

    [ https://issues.apache.org/jira/browse/NIFI-7161?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17516629#comment-17516629 ]

-----------------------------

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 

NIsha

> *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."_
