Zabbix

What is Zabbix​

From https://www.zabbix.com/features

note

Zabbix is the ultimate enterprise-level software designed for real-time monitoring of millions of metrics collected from tens of thousands of servers, virtual machines and network devices.

Zabbix is Open Source and comes at no cost.

Preparation​

The following placeholders will be used:

  • zabbix.company is the FQDN of the Zabbix install.
  • authentik.company is the FQDN of the authentik install.

Create an application in authentik and note the slug, as this will be used later. Create a SAML provider with the following parameters:

  • ACS URL: https://zabbix.company/zabbix/index_sso.php?acs
  • Issuer: zabbix
  • Service Provider Binding: Post

You can of course use a custom signing certificate, and adjust durations.

Zabbix Configuration​

Navigate to https://zabbix.company/zabbix/zabbix.php?action=authentication.edit and select SAML settings to configure SAML.

Check the box to enable SAML authentication.

Set the Field IdP entity ID to zabbix.

Set the Field SSO service URL to https://authentik.company/application/saml/zabbix/sso/binding/redirect/.

Set the Field Username attribute to http://schemas.goauthentik.io/2021/02/saml/username

Set the Field SP entity ID to https://authentik.company/application/saml/zabbix/sso/binding/redirect/

Set the Field SP name ID format to urn:oasis:names:tc:SAML:2.0:nameid-format:transient

Check the box for Case sensitive login.

For the SAML Service Provider Certificate and SAML Service Provider Private Key, you can either use custom certificates, or use the self-signed pair generated by authentik.

Copy the cert and key to /usr/share/zabbix/conf/certs/, the system looks for sp.key and sp.crt by default.

The certificate path can be configured in the Zabbix frontend configuration file (zabbix.conf.php)

$SSO['SP_KEY'] = '<path to the SP private key file>';
$SSO['SP_CERT'] = '<path to the SP cert file>';

For additional security you can enable the Verification Certificate by checking the Sign -> AuthN requests in the Zabbix configuration and adding the IDP Certificate to the cert path above or defining it in your Zabbix frontend configuration file.

$SSO['IDP_CERT'] = '<path to the IDP cert file>';
