How to configure Grafana to authenticate against an external system on Vultr?

To configure Grafana to authenticate against an external system on Vultr, you can follow these steps:

1. Firstly, install Grafana on your Vultr server by following the appropriate installation guide for your operating system. You can find installation guides on the Grafana website.
2. Once Grafana is installed, open the Grafana configuration file. The location of this file will depend on your operating system, but it is commonly located at /etc/grafana/grafana.ini.
3. In the configuration file, locate the [users] section.
4. Uncomment the allow_sign_up option by removing the semicolon (;) at the beginning of the line, and set it to false. This will disable user sign-ups.
5. Set the auto_assign_org option to false. This will prevent new users from being automatically assigned to an organization and require manual assignment.
6. Save the configuration file and exit.
7. Next, you need to set up an external system that will handle the authentication process. Vultr does not provide a built-in authentication system, so you will need to set up an external tool like OAuth, LDAP, or an identity provider.
8. Once the external system is set up and configured, obtain the required credentials or configuration details to integrate it with Grafana. This may include client IDs, client secrets, authorization URLs, token URLs, etc., depending on the authentication method you choose.
9. Now, go to the Grafana web interface by accessing the Grafana server's IP address or domain name in your web browser.
10. Login to Grafana as an admin user.
11. In the Grafana interface, click on the gear icon on the left-hand side to open the configuration menu, and then click on "Auth" under the "Server" section.
12. In the "Auth" settings page, choose your external system from the available authentication options (OAuth, LDAP, etc.) and configure the necessary fields such as URLs, client IDs, and secrets based on the information obtained from the external system.
13. Save the settings, and Grafana should now be configured to authenticate against the external system on Vultr.
14. Test the configuration by logging out of Grafana and trying to log in again using the credentials from the external system.

Note: The specific steps and options may vary depending on the version of Grafana you are using and the external authentication method chosen. Always refer to the official Grafana documentation for accurate and up-to-date information.
