I Use Kibana 7.11.1 stack. this problem is related to elasticsearch alone.
I added xpack.security.enabled: true to elasticsearch.yml and ran elasticsearch-setup-passwords auto
to set the default users password. but now when I start elasticsearch I keep seeing the message:
[o.e.x.s.a.AuthenticationService] [SERVER_NAME] Authentication of [elastic] was terminated by realm [reserved] - failed to authenticate user [elastic]
i see this only when elasticsearch service is up, so I assumed that I need to set the new elastic user password in elasticsearch.yml file, but i have no idea how..
any ideas ?
thanks
The error message indicates that the credentials with which you are trying to authenticate do not match the saved username and password.
After turning on the xpack.security.enabled setting, you can set the built-in user credentials, using the below command
bin/elasticsearch-setup-passwords interactive
I missed one service that is part of the kibana stack. the elastic-agent.
so the database wasn't trying to connect to itself! :) elastic-agent was trying to connect to elasticsearch without the proper credentials.
once i resolved that and restart elastic-agent, the problem resolved.

I am facing an issue while connecting filebeats with my trial version of elastic cloud.
I am getting below error
ERROR pipeline/output.go:100 Failed to CLOUD_ID): 401 Unauthorized:
{"error":{"root_cause":[{"type":"security_exception","reason":"unable to authenticate user
[USER_EMAIL] for REST request [/]","header":{"WWW-Authenticate":["Basic realm=\"security\"
charset=\"UTF-8\"","Bearer realm=\"security\"","ApiKey"]}}],"type":"security_exception","reason":
"unable to authenticate user ...
I have attached my filebeat.yml too. Please look.
I crossed check my username and password both are correct.
please help!
Here my cloud credentials don’t look right. The syntax for cloud.auth is user:password
It needs to be the cluster credentials, not the cloud account credentials. (Default username is elastic, and you’re presented a randomly generated password when the cluster is created)
I have Es version 7.6.2 I saw on website that from version 6.2 onwards x-pack is included by default but i was not able to find or enable x-pack for security. how do i enable password protection in Elastic search.
As per elastic search documentation
The first thing you have to do is download the default distribution of
Elasticsearch and Kibana version 6.8+ or 7.1+. Security was added to
the default distribution in 7.1 and 6.8, so if you’re on an older
version, you’ll need to upgrade.
After downloading latest version , you need to enable xpack.security.enabled: true in elasticsearch.yml file
To generate passwords
elasticsearch-setup-passwords auto
in command prompt, your cmd path should be elasticsearch/bin. It will auto generate passwords for elasticsearch kibana etc. note them .
If you want to provide your own username password instead of auto generated execute
elasticsearch-setup-passwords interactive
In kibana.yml update below two with user name and password for elastic search you got by executing set up password
elasticsearch.username: "<elastic>"
elasticsearch.password: "<password>"
Opening kubana it will prompt for username and password, enter password for "kibana" you got from set-up-password
I am able to password protect ES however my kibana is now asking for UID and password when opened. The ES credentials dont work on the kibana screen. What password does Kibana looking for ?
isseue resolved by using elastic user rather than kibana user
I've started learning elasticsearch using AWS I followed this article to create elasticsearch and Kibana setup
After completing the setup, tried to log in using my user from user pool, after login I'm getting error "Missing Role"
url https://search-mytestdomain-xxxxxxxxxxxxxxxxxxxxxx.us-east-2.es.amazonaws.com/_plugin/kibana/customerror?type=missingRole#?_g=()
Was looking all over for the fix after following the same guide you linked. Came across this post during my searching and wanted to update my fix for that specific guide is to use Elasticsearch 6.2 when creating the domain.
I haven't tried any other versions but when I switched from ES 7.4 (latest) to 6.2 (which is mentioned in the guide) it worked with no issues.
What worked for me is below on ES 7.4,
Open Identity Pool
Click "Edit identity pool"
Authentication Providers
Authenticated Role Section
Choose role from token
Role resolution: DENY
This document had the answer that worked for me:
https://docs.aws.amazon.com/elasticsearch-service/latest/developerguide/fgac.html#fgac-walkthrough-iam
The real issue was that the role I was using on the identity pool and elasticsearch cluster did not have a trust relationship policy to allow the identity pool to assume the role. So login was succeeding, but the pool wasn't able to assume the role, and therefore there really was a missing role on the token that Kibana was receiving. Adding the trust relationship policy shown in step 4 of the doc in addition to the policy allowing kibana to assume the role, fixed the missing role issue for me and successfully passed my authenticated user into kibana's main interface.
I just set up authentication on a newly installed ES stack.
I followed:
https://www.elastic.co/guide/en/elastic-stack-overview/current/get-started-enable-security.html
I tried logging into kibana as user 'kibana'
I encountered {"statusCode":403,"error":"Forbidden","message":"Forbidden"}
Answer:
Login as elastic
that simple
username : elastic
password : changeme # or what ever password you kept while enabling xpack
Basic username/password authentication for ELK, i was able to achieve using searchguard on windows platform.
Now i am trying to establish secure communication. I have performed the following changes,
In elasticsearch.yml
searchguard.ssl.http.enabled: true
searchguard.ssl.http.keystore_filepath: D:\Softwares\ELK\elasticsearch-5.4.0\elasticsearch-5.4.0\config\CN=localhost-keystore.jks
searchguard.ssl.http.keystore_password: 221749a2add117cf889f
searchguard.ssl.http.truststore_filepath: D:\Softwares\ELK\elasticsearch-5.4.0\elasticsearch-5.4.0\config\truststore.jks
searchguard.ssl.http.truststore_password: 6d6cf1cc017dc874960b
searchguard.authcz.admin_dn:
- CN=sgadmin
searchguard.ssl.transport.keystore_filepath: D:\Softwares\ELK\elasticsearch-5.4.0\elasticsearch-5.4.0\config\CN=localhost-keystore.jks
searchguard.ssl.transport.keystore_password: 221749a2add117cf889f
searchguard.ssl.transport.truststore_filepath: D:\Softwares\ELK\elasticsearch-5.4.0\elasticsearch-5.4.0\config\truststore.jks
searchguard.ssl.transport.truststore_password: 6d6cf1cc017dc874960b
In Kibana.yml
elasticsearch.url: "https://localhost:9200"
elasticsearch.username: "admin"
elasticsearch.password: "admin"
If i login to kibana, using http://localhost:5601, it asks for username and password. I dont know what credentails to enter here. i tried admin/admin. Its not working. Before i gave searchguard.ssl.http.... configurations, admin/admin was working fine.
After i added all the searchguard.ssl.http related configuration, the credentails are not working.
I am sure there is some other configuration in kibana.yml w.r.t searchguard configuration. I am not able to find it online. Can any one please help me here on what is missing.
Enabling TLS on the REST layer does not have any impact on user authentication/authorisation. The only difference is:
If you enable TLS on REST layer, only HTTPS access is allowed. You will see an error message if you try to access ES with HTTP
If you disable TLS on REST layer, only HTTP access is allowed. You will see an error message if you try to access ES with HTTPS.
Search Guard will authenticate the credentials against the configured authentication backend in sg_config.yml. If you use the default configuration that ships with Search Guard, it will use the internal user database and the users defined in internal_users.yml. The default "admin" user has full access to all indices and types, so you should be able to use this user to log into Kibana. If you need a user with limited access, the corresponding demo user is "kibanaro". Please refer to internal_users.yml to see all demo users.
Since ES 5.0.2, you need to install the Search Guard Kibana plugin for full authentication and session support. You can find the plugin on the corresponding GitHub repository. You install it like any other Kibana plugin, for example:
bin/kibana-plugin install https://github.com/floragunncom/search-guard-kibana-plugin/releases/download/v5.4.3-3/searchguard-kibana-5.4.3-3.zip
If you do not need advanced stuff like multi-tenancy or JWT Single Sign-on, it should start and work out of the box.
If this does not help, please post the output of your Elasticsearch log files when trying to log in.
Disclaimer: I work for floragunn, makers of Search Guard.
