If you are using Access Manager as the authentication service for Identity Governance, you can use Access Manager to configure the products in your IT environment to provide a single sign-on experience for the users using Identity Governance or any other product you have installed. One of the features of Access Manager is that it contains a single sign-on solution.
To provide single sign-on to Identity Governance you must configure Identity Governance as a trusted provider in Access Manager. If you are running Identity Governance and Identity Manager, you can configure both products to be trusted providers in Access Manager and any time an authorized user accesses Identity Governance, Identity Reporting, Workflow Engine or any identity applications, they have a single sign-on experience. For more information, see Configuring Trusted Providers for Single Sign-On
in the NetIQ Access Manager 5.0 Administration Guide.
