  • On GitHub you can click on Test SAML Configuration and then on Save


  • Single sign-on in GitHub authenticates to a specific organization in GitHub and does not replace the authentication of GitHub itself. Therefore, if the user's session has expired, you may be asked to authenticate with GitHub's ID/password during the single sign-on process

  • By using SSO, a user could automatically join the GitHub organization even if not invited previously

  • To sum up, on GitHub SSO allows to access an organization easily but does not replace the manual authentication of the user
