If you are using Oracle Access Manager or SiteMinder (or a custom SSO provider) as the web identity management solution, use an HTTP header to pass the login name of the authenticated user to EPM System products.
The login name of an EPM System product user is determined by the Login Attribute that is specified while configuring user directories in Shared Services. See “Configuring OID, Active Directory, and Other LDAP-Based User Directories” in the Oracle Hyperion Enterprise Performance Management System User and Role Security Guide for a brief description of the Login Attribute.
The HTTP header must contain the value of the attribute that is set as the Login Attribute. For example, if uid is the Login Attribute value, the HTTP header must carry the value of the uid attribute.
See your web identity management solution documentation for detailed information on defining and issuing custom HTTP headers.
EPM System security parses the HTTP header and validates the login name that it carries against the user directories configured on Shared Services.
