Before we look at more detailed user configuration, it might be helpful to know that Zabbix supports three authentication methods. Navigate to Administration | Authentication to take a look at authentication configuration:

As can be seen in the preceding screenshot, these are the three authentication methods:

• HTTP: Users are authenticated with web server HTTP authentication mechanisms. Support for HTTP authentication basically allows the use of any of the authentication methods for Zabbix that the web server supports, and in the case of the Apache HTTPD daemon, there are many. If you like to use HTTP authentication, then click the HTTP settings tab and fill in the necessary information.
• LDAP: Users are authenticated using an LDAP server. This can be handy if all enterprise users that need access to Zabbix are already defined in an LDAP structure. Only user passwords are verified; group membership and other properties are not used. A Zabbix user account must also exist for the login to be successful. If you would like to use the LDAP authentication, then you will need to fill in the settings in the LDAP tab and select LDAP from the Authentication page instead of internal.

• Internal: With this method, users are authenticated using Zabbix's internal store of users and passwords. We will be using this method.
