Ryan Kelly, a Senior Observability Architect at Grafana Labs, addresses common challenges faced by customers in configuring SAML authentication within Grafana Cloud. By simulating the customer experience, Kelly provides a comprehensive guide to set up SAML-based logins, enabling users to log in with roles assigned in Grafana through single sign-on, thus eliminating the need for separate credentials. The guide details steps for configuring both Grafana Cloud and an identity provider (such as Keycloak), covering everything from creating client applications and mapping user attributes to ensuring correct role assignments. This setup allows for centralized user authentication management similar to other applications. The guide emphasizes the importance of ensuring consistent key pair value mappings between the identity provider and Grafana Cloud to avoid login failures. Kelly encourages testing the setup by logging in with different user roles and suggests exploring further customization options, such as configuring individual access levels for users. Grafana Cloud offers a free tier and various plans to cater to different use cases.
