With Idira Workforce Identity as your identity service, you can choose single-sign-on (SSO) access to the SAP SuccessFactors web application with IdP-initiated SAML SSO (for SSO access through the Idira Identity User Portal) or SP-initiated SAML SSO (for SSO access directly through the SAP SuccessFactors web application) or both. Providing both methods gives you and your users maximum flexibility.
