  1. Set SAML_DATABASE_URL to a Postgres database. Please use a different database than the main Cal instance since the migrations are separate for this database. For example postgresql://postgres:@localhost:5450/cal-saml. If you are using a self-signed certificate for Postgres then use the sslmode=no-verify query param in the database URL. For example postgresql://postgres:@localhost:5450/cal-saml?sslmode=no-verify.
  2. Set SAML_ADMINS to a comma separated list of admin emails who can configure the OIDC.
  3. Create an application with your OIDC provider. For example, in Okta, once you create an account, you can click on Applications on the sidebar menu:
  4. Click on Create App Integration
  5. Select OIDC in the modal form, along with Web App and click Next.
  6. Enter the Sign in redirect URL (or auth URL) as 
      {BASE_URL}/api/auth/oidc
    And the sign out URL as 
      {BASE_URL}/auth/login
    where is your app’s base URL, and click save.
    Please replace {BASE_URL} here with respective URL, such as localhost:3000 for localhost testing, for example.
  7. Now you should have the Client Secret and Client ID with you. You would also need the Well Known URL which for Okta is generally of the type: 
    https://{yourOktaDomain}/.well-known/openid-configuration
    So, if your okta domain is dev-123456.okta.com, your well known URL would be 
    https://dev-123456.okta.com/.well-known/openid-configuration
  8. Now spin up cal.com on your server and login with the Admin user (the email ID of which was provided in step 2 for SAML_ADMINS environment variable).
  9. Visit {BASE_URL}/settings/security/sso and you should see something like this:
  10. Click on Configure SSO with OIDC, and then enter the Client Secret, Client ID and Well known URL from the Step 7, and click save.
