The Oracle ATG Web Commerce can be configured to use Single Sign On (SSO), using Oracle Access Management (OAM). This feature enables the ATG Business Control Center and the Endeca Workbench to share logins, so that when a user logs into one of these environments, that user is automatically also logged into the other environment as well. You can use OAM SSO to authenticate internal users of Oracle ATG Web Commerce Business Control Center, and Oracle Endeca Workbench using a single authentication step.
For more information, see Appendix D: Using Oracle Access Management for Single Sign On in the Commerce Service Center Installation and Programming Guide and the Commerce Single Sign-On chapter of the ATG-Endeca Integration Guide.
