Zabbix Web With OpenLDAP

This example is for the Zabbix Web interface version 6.0, which is the supported LTS version as of August 2023. Later versions have additional options.

For the associated 6.0 documentation see here and for the current manual see here.

Note that an LDAP user must exist in Zabbix Web as well, however its Zabbix password will not be used. When creating the user in Zabbix, the user should also be added to your desired Zabbix roles/groups.

Configure LDAP Settings

Log in to the web interface as an admin
Navigate to Administration > Authentication > LDAP Settings

Enable LDAP authentication

Checked

LDAP host

URI of your OpenLDAP host. Example: ldap://ldap.example.com:389 or ldaps://ldap.example.com:636 for TLS.

Port

Not used when using a full LDAP URI as above, but feel free to put 389 or 636 for TLS.

Base DN

Your OpenLDAP_LDAP_BASE. Example: dc=example,dc=com

Search attribute

uid

Checked

Bind DN

uid=admin,ou=people,dc=example,dc=com

Alternately, it is recommended that you create a separate user account (e.g, bind_user) instead of admin for sharing Bind credentials with other services. The bind_user should be a member of the ldap_strict_readonly group to limit access to your LDAP configuration in OpenLDAP.

Bind password

Password for the above bind DN user.

Test authentication

The test authentication Login and User password must be used to check the connection and whether an LDAP user can be successfully authenticated. Zabbix will not activate LDAP authentication if it is unable to authenticate the test user.

Enable LDAP in Zabbix Web

Navigate to Administration > Authentication > Authentication (the first tab)
Set “Default authentication” to “LDAP”
Click “Update”
