To enable Single Sign-On using Google Apps, follow the steps in Google's Help Center: https://support.google.com/a/answer/6363766?hl=en.
Once everything is up and running, please note:
- All users must log in through Google Apps once SSO is enabled. Users will be able to log in via the normal Greenhouse Recruiting login screen anymore, even if they already have passwords.
- If a new user has a Google Apps account but not a Greenhouse Recruiting account, Greenhouse will automatically create a Greenhouse Recruiting user account the first time they log in via Google Apps. The user account will be created with Basic permissions. Administrators can still invite users and change permissions in Greenhouse Recruiting using the existing process.
- Data will be unaffected. Your users will still have access to all of their existing jobs, scorecards, interviews, etc. Google Apps only changes the way people log in.
