The discussion ultimately evolved into a discussion about authentication and access control methods employed by various organization to access their Google Apps Standard/Premier/Education accounts. We started talking and comparing Multi-factor authentication, SAML based SSO, OpenId, native Google Authentication etc. I would like to query slashdot readers who use Google Apps about the authentication method their organization currently employees and why. Also please take 2 minutes to answer a brief survey. The result summary of the survey is available here"
