If you want to use Google OAuth to authenticate users, you need to create a Google Developers project (see the instructions (https://redash.io/help/open-source/admin-guide/google-developer-account-setup) for this and then add the following configuration in the env file):

export REDASH_GOOGLE_CLIENT_ID=""
export REDASH_GOOGLE_CLIENT_SECRET=""

Once enabled, Redash will use Google OAuth to authenticate existing user accounts. In order to enable automatic user creation according to a specific domain name, you can add this domain in the setting page.

If you're passing multiple domains, separate them with commas:

1. Restart the web server to apply the configuration changes: docker-compose up -d.
2. Once you have Google OAuth enabled, you can log in using your Google Apps account. If you want to grant admin permissions to some users, you can do this by adding them to the admin group (from the /groups page).
3. If you don't use Google OAuth or just need username/password logins, you can create additional users by opening the /users/new page.
