Wazuh authentication using VeridiumID over SAML

This tutorial demonstrates how to configure Wazuh authentication using VeridiumID as a SAML Identity Provider. It covers the integration of SAML-based Single Sign-On (SSO) for centralized authentication, along with a fallback to internal users to ensure continued access in case SAML is unavailable.

Generate SP Cert / Key

openssl req -x509 -newkey rsa:2048 -keyout /etc/wazuh-indexer/certs/sp-key.pem   -out /etc/wazuh-indexer/certs/sp-cert.pem -days 3650 -nodes   -subj "/CN=wazuh-dashboard"
chown wazuh-indexer:wazuh-indexer /etc/wazuh-indexer/certs/sp-cert.pem
chown wazuh-indexer:wazuh-indexer /etc/wazuh-indexer/certs/sp-key.pem

Configure VeridiumID

From “Veridium Manager , go to Applications → Add SAML app and we need to complete the following parameters:

Enable or disable the SAML service provider: enable
Entity ID: wazuh-dashboard
Service Provider Name: WazuhDashboard
Service Provider Friendly Name: WazuhDashboard
Metadata Upload Type: File
Metadata File (save the below XML local and replace the content) after that upload it.

Please replace “ds:X509Certificate” with content from /etc/wazuh-indexer/certs/sp-cert.pem (without -----BEGIN CERTIFICATE----- and -----END CERTIFICATE-----)

Please replace wazuh.dev.local, with your Wazuh Dashboard Kibana url.

Configure Wazuh

Login to Wazuh Server via SSH and edit the following files:
Edit /etc/wazuh-indexer/opensearch-security/config.yml

Add “saml_auth_domain” as below and change the parameters.

    authc:
      saml_auth_domain:
        http_enabled: true
        transport_enabled: false
        order: 1
        http_authenticator:
          type: saml
          challenge: true
          config:
              idp:
                metadata_url: "https://shib-domain-veridiumid.com/idp/shibboleth"
                entity_id: "https://shib-domain-veridiumid.com/idp/shibboleth"
              sp:
                entity_id: "wazuh-dashboard"
                signature_private_key_filepath: "/etc/wazuh-indexer/certs/sp-key.pem"
                forceAuthn: false
              kibana_url: "https://wazuh.dev.local"
              roles_key: memberOf
              exchange_key: "69fd6xx57e4451f8xx3d8a1061"
                #logout_url: ""
        authentication_backend:
            type: noop
      basic_internal_auth_domain:
        description: "Authenticate via HTTP Basic against internal users database"
        http_enabled: true
        transport_enabled: true
        order: 0
        http_authenticator:
          type: basic
          challenge: false
        authentication_backend:
          type: intern

idp → metadata_url: metadata url https://shib-domain-veridiumid.com/idp/shibboleth"
idp → entity_id:
- From “Veridium Manager , go to “Settings → Identify Provider → SAML → Entity Id*

in our case https://shib-domain-veridiumid.com/idp/shibboleth

ssp → entity_id: wazuh-dashboard (entity_id from Veridium Manager → Applications → WazuhDashboard (our saml configuration) → Entity ID.
ssp → signature_private_key_filepath → path to the sp key, in our case /etc/wazuh-indexer/certs/sp-key.pem
kibana_url: https://wazuh.dev.local (wazuh url kibana)
roles_key: memberOf (in our case we will have wazuh_admins group as part of memberOf)
exchange_key: (we can generate it using “openssl rand -hex 32” command

We need to set the order of “saml_auth_domain” to 1 and “basic_internal_auth_domain” to 0.

Edit /etc/wazuh-dashboard/opensearch_dashboards.yml

opensearch_security.auth.type: ["basicauth", "saml"]
opensearch_security.auth.multiple_auth_enabled: true
server.xsrf.whitelist: ["/_opendistro/_security/saml/acs", "/_opendistro/_security/saml/acs/idpinitiated", "/_opendistro/_security/saml/logout"]
opensearch.username: "admin"
opensearch.password: "admin"
opensearch_security.auth.logout_url: "https://wazuh.dev.local/login"

opensearch.username: replace with the correct user, local

opensearch.password: replace with the correct password, local user

Important behavior:

basicauth → used for API/internal login
saml → used for browser login
challenge: false on basic → prevents browser popup

Edit /etc/wazuh-indexer/opensearch-security/roles_mapping.yml

all_access:
  reserved: true
  hidden: false
  backend_roles:
    - "CN=wazuh_admins,OU=AADDC Users,DC=veridiumid,DC=com"
    - "admin"
  hosts: []
  users: []
  and_backend_roles: []
  description: "Maps admin to all_access"

If we have A hybrid Active Directory (AD) we can add multiple backend_roles CN like below:

- "CN=wazuh_admins,OU=AADDC Users,DC=mydomain,DC=com"
- "CN=wazuh_admins,OU=Groups,OU=MyDomain,DC=mydomain,DC=local"

Remember to add users to the “wazuh_admins” group.

Update the changes and restart the services.

This command sets the Java environment for Wazuh Indexer and runs the securityadmin.sh tool to apply or update OpenSearch Security configurations using the administrator certificates.

export OPENSEARCH_JAVA_HOME=/usr/share/wazuh-indexer/jdk

/usr/share/wazuh-indexer/plugins/opensearch-security/tools/securityadmin.sh \
  -cd /etc/wazuh-indexer/opensearch-security/ \
  -icl -nhnv \
  -cacert /etc/wazuh-indexer/certs/root-ca.pem \
  -cert /etc/wazuh-indexer/certs/admin.pem \
  -key /etc/wazuh-indexer/certs/admin-key.pem

systemctl restart wazuh-indexer
systemctl restart wazuh-dashboard

Verify SAML works

journalctl -u wazuh-dashboard -n 20

You should NOT see:

backend_roles=[]
