By default, Identity Manager uses OSP for single sign-on access in Identity Manager. When you install Identity Reporting and the identity applications, you specify the basic settings for user authentication. However, you can also configure the OSP authentication server to accept authentication from the Kerberos ticket server or SAML IDP. For example, you can use SAML to support authentication from NetIQ Access Manager. For more information about OSP, see Using Single Sign-on Access in Identity Manager.
