Hi All,

WE have configured elastic stack by mentioning the IP address in all the config files and we have done OKta integration also. Now we have done a DNS entry for the IP address used, after this change we are not able to access kibana console through Okta authentication.

Below is the error we are getting.

`{"statusCode":401,"error":"Unauthorized","message":"[security_exception] unable to authenticate user [<unauthenticated-saml-user>] for action [cluster:admin/xpack/security/saml/authenticate], with { header={ WWW-Authenticate={ 0=\"Bearer realm=\\\"security\\\"\" & 1=\"Basic realm=\\\"security\\\" charset=\\\"UTF-8\\\"\" } } }"}`

Through local login i was able to login. Problem is with Okta authentication.

Any advice please.

Thanks  
Gautham

Hi @Gauti,

Have you properly reconfigured Elasticsearch SAML realm to work with DNS names instead of IPs? Does Okta metadata file/URL you use in Elasticsearch configuration also reflect that change?

Also you should be able to locate a more detailed error message in the [Elasticsearch logs](https://www.elastic.co/guide/en/elasticsearch/reference/current/trb-security-saml.html).

Let me know if you still have any questions,  
Oleg
