What Is Keycloak?
Keycloak is an open-source identity and access management solution that provides features such as single sign-on (SSO), identity brokering, user federation, and social login. It allows developers to secure applications and services with minimal effort. With Keycloak, organizations can manage user identities across multiple applications, enabling centralized authentication and authorization.
Key Features of Keycloak
- Single Sign-On: Users can authenticate once and gain access to multiple applications without needing to log in again.
- User Federation: Integrate with existing user databases, including LDAP and Active Directory.
- Identity Brokering: Enable users to authenticate using external identity providers like Google, Facebook, and more.
- Customizable Authentication Flows: Tailor the authentication experience to meet specific organizational needs.
What Is Snowflake?
Snowflake is a cloud-based data warehousing platform designed for scalability, flexibility, and ease of use. It allows organizations to store and analyze vast amounts of data efficiently. Snowflake’s architecture separates storage and compute, enabling users to scale resources independently based on their needs.
Key Features of Snowflake
- Elastic Scaling: Automatically scales up or down based on workload demands.
- Multi-Cloud Support: Operate across different cloud providers, including AWS, Azure, and Google Cloud.
- Data Sharing: Securely share data in real time across different organizations or departments.
- Support for Structured and Semi-Structured Data: Handle diverse data types, including JSON, Avro, and Parquet.
Step 1: Setting Up Keycloak
Install Keycloak
Download Keycloak: Go to the Keycloak website and download the latest version.
Install Keycloak: Follow the installation instructions for your operating system. For example, on Linux, you can extract the downloaded file and run the standalone server with the command:
Create a Realm
Log in to the Keycloak Admin Console: Open your browser and navigate to http://localhost:8080/auth/admin/.
Create a New Realm: In the admin console, click on the “Add Realm” button and enter a name for your realm (e.g., snowflake-realm).
Create a Client
Navigate to Clients: In the realm settings, click on “Clients” from the left menu.
Create a New Client: Click on “Create” and enter the client ID (e.g., snowflake-client), then select the client protocol as openid-connect.
Configure Client Settings
Set Redirect URIs: Under the “Settings” tab, configure the “Valid Redirect URIs” to allow Snowflake to redirect back after authentication. For example:
Enable Client Authentication: Ensure that “Client Authentication” is enabled for secure communication.
Step 2: Setting Up Snowflake
Create a Snowflake Account
Sign Up for Snowflake: If you don’t already have an account, sign up at the Snowflake website.
Log In to Snowflake: Access your Snowflake account with the provided credentials.
Create a User and Role
Create a User: In the Snowflake web interface, navigate to the “Users” section and create a new user that will be linked to Keycloak.
Create a Role: Under the “Roles” section, create a role that the user will assume for accessing data.
Step 3: Configuring The Integration
Configure Identity Provider in Keycloak
Add a New Identity Provider: In the Keycloak admin console, go to “Identity Providers” and select “OpenID Connect”.
Configure Provider Settings:
-
- Alias: Enter a name for the provider (e.g.,
snowflake-provider). - Client ID: Enter the client ID you created in the Snowflake OIDC application.
- Client Secret: Enter the client secret generated by Snowflake.
- Authorization URL: Set it to
https://<your-snowflake-account>.snowflakecomputing.com/oauth2/v1/authorize. - Token URL: Set it to
https://<your-snowflake-account>.snowflakecomputing.com/oauth2/v1/token. - User Info URL: Set it to
https://<your-snowflake-account>.snowflakecomputing.com/oauth2/v1/userinfo.
- Alias: Enter a name for the provider (e.g.,
Create an OIDC Application in Snowflake
Log in to Snowflake: Access your Snowflake account.
Create an OIDC Application: Navigate to the “Admin” tab, then to “Integrations”, and select “Create” under OIDC Applications.
Configure the Application:
-
- Name: Enter a name for your application (e.g.,
keycloak-snowflake-app). - Redirect URI: Enter the redirect URI from your Keycloak client settings.
- Name: Enter a name for your application (e.g.,
Step 4: Testing The Configuration
To ensure that your Keycloak and Snowflake integration is working correctly, perform the following tests:
Access the Snowflake Account: Open a Web browser and navigate to your Snowflake account URL.
Authenticate with Keycloak: You should be redirected to the Keycloak login page. Enter your credentials and log in.
Access Snowflake Data: After authentication, you should have access to your Snowflake data based on the roles and permissions configured.
Step 5: Troubleshooting Common Issues
While configuring Keycloak with Snowflake, you might encounter a few common issues. Here are some troubleshooting tips:
- Invalid Redirect URI: Ensure that the redirect URI in Keycloak matches the one specified in Snowflake.
- Client Secret Issues: Double-check that the client secret used in Keycloak matches the one generated in Snowflake.
- User Role Access: Make sure the user you created in Snowflake has the appropriate roles and permissions.
Conclusion
Integrating Keycloak with Snowflake provides a robust identity and access management solution that enhances security and user experience. By following this step-by-step guide, you can successfully configure Keycloak to manage user authentication and authorization for your Snowflake account, ensuring that your data remains secure while being easily accessible to authorized users.

How does Keycloak integrate with Snowflake?
Keycloak integrates with Snowflake by acting as an Identity Provider (IdP) using the OpenID Connect (OIDC) protocol. This integration allows users to authenticate through Keycloak, enabling secure access to Snowflake data while managing user identities centrally.
What are the prerequisites for configuring Keycloak with Snowflake?
To configure Keycloak with Snowflake, you need a running instance of Keycloak, a Snowflake account, admin access to both platforms, and a basic understanding of IAM concepts and OIDC.
Can I use Keycloak for user management in Snowflake?
Yes, Keycloak can manage user identities and authentication for Snowflake. By configuring Keycloak as the Identity Provider, you can centralize user management and secure access to your Snowflake data.
What should I do if I encounter issues during the integration process?
If you encounter issues during integration, check the redirect URIs, verify client secrets, and ensure that the created user has the appropriate roles and permissions in Snowflake. Additionally, consult Keycloak and Snowflake documentation for further troubleshooting guidance.
