You must set security options in Shared Services to force EPM System to use the custom login class to authenticate users. The following procedure explains only the steps that you must take to enable the use of the custom login class. See “Setting Security Options” in the Oracle Hyperion Enterprise Performance Management System User and Role Security Guide.
EPM System provides com.hyperion.css.sso.agent.X509CertificateSecurityAgentImpl to extract the user identity (DN) from x509 certificates.
If you must derive user identity from a certificate attribute other than DN, you must develop and implement a custom login class. See Implementing a Custom Login Class.
