SAML SSO Setup

Note

SAML SSO is in private preview. Please contact [email protected] to see if this is available for your organization.

ClickHouse Cloud supports single-sign on (SSO) via security assertion markup language (SAML). This enables you to sign in securely to your ClickHouse Cloud organization by authenticating with your identity provider (IdP).

We currently support service provider initiated SSO, multiple organizations using separate connections, and just-in-time provisioning. We do not yet support system for cross-domain identity management (SCIM) or attribute mapping.

Before you begin

You will need Admin permissions in your IdP and the Admin role in your ClickHouse Cloud organization. After setting up your connection within your IdP, contact us with the information requested in the procedure below to complete the process.

We recommend setting up a direct link to your organization in addition to your SAML connection to simplify the login process. Each IdP handles this differently. Read on for how to do this for your IdP.

How to Configure Your IdP

All IdPs

All setups require your organization ID. To obtain your organization ID:

  1. Sign in to your ClickHouse Cloud organization.

How It Works

Service Provider Initiated SSO

We only utilize service provider initiated SSO. This means users go to `https://console.clickhouse.cloud`` and enter their email address to be redirected to the IdP for authentication. Users already authenticated via your IdP can use the direct link to automatically log in to your organization without entering their email address at the login page.

Assigning User Roles

Users will appear in your ClickHouse Cloud console after they are assigned to your IdP application and log in for the first time. At least one SSO user should be assigned the Admin role in your organization. Use social login or https://clickhouse.cloud?with=email to log in with your original authentication method to update your SSO role.

Removing Non-SSO Users

Once you have SSO users set up and have assigned at least one user the Admin role, the Admin can remove users using other methods (e.g. social authentication or user ID + password). Google authentication will continue to work after SSO is set up. User ID + password users will be automatically redirected to SSO based on their email domain unless users use https://clickhouse.cloud?with=email.

Managing Users

ClickHouse Cloud currently implements SAML for SSO. We have not yet implemented SCIM to manage users. This means SSO users must be assigned to the application in your IdP to access your ClickHouse Cloud organization. Users must log in to ClickHouse Cloud once to appear in the Users area in the organization. When users are removed in your IdP, they will not be able to log in to ClickHouse Cloud using SSO. However, the SSO user will still show in your organization until and administrator manually removes the user.

Multi-Org SSO

ClickHouse Cloud supports multi-organization SSO by providing a separate connection for each organization. Use the direct link (https://console.clickhouse.cloud?connection={organizationid}) to log in to each respective organziation. Be sure to log out of one organization before logging into another.

Additional Information

Security is our top priority when it comes to authentication. For this reason, we made a few decisions when implementing SSO that we need you to know.

  • We only process service provider initiated authentication flows. Users must navigate to https://console.clickhouse.cloud and enter an email address to be redirected to your identity provider. Instructions to add a bookmark application or shortcut are provided for your convenience so your users don't need to remember the URL.

  • All users assigned to your app via your IdP must have the same email domain. If you have vendors, contractors or consultants you would like to have access to your ClickHouse account, they must have an email address with the same domain (e.g. [email protected]) as your employees.

  • We do not automatically link SSO and non-SSO accounts. You may see multiple accounts for your users in your ClickHouse user list even if they are using the same email address.
