Can Grafana open source be used for SAML authentication?

because on building the open source grafana project locally i see there is no authentication tab present.

Note: Available in Grafana Enterprise and Grafana Cloud Pro and Advanced.

So SAML auth feature is not available in Grafana Open Source.

But you can use auth proxy feature and use SAML in front of Grafana in your SAML auth proxy. It won’t be straightforward, but it is possible.
