External authentication means that the user login information needed by Analytic Services is maintained in a central authentication directory, such as Lightweight Directory Access Protocol (LDAP) Directory, Microsoft Active Directory, or Windows NT LAN Manager.
An authentication directory is a centralized store of user information such as login names and passwords, and other corporate information. The repository functions like a telephone directory. The authentication directory probably contains much more than user names and passwords; for example, it may include e-mail addresses, employee IDs, job titles, access rights, and telephone numbers. It may also contain objects other than users; for example, it may contain information about corporate locations or other entities.
To use the security platform for Analytic Services, your organization must have an authentication directory that contains corporate user information. Additionally, you must employ an XML-based security configuration file to specify correct information pertaining to your corporate authentication directory.
The following types of authentication repositories are supported by the security platform:
Note: Prior to this release, Analytic Services provided support for external authentication using built-in modules. Those modules did not include the ability to share the same external authentication scheme with other Hyperion software applications or to enable single sign-on to Analytic Services from other Hyperion applications. Support for the earlier modules is unaffected by the new security platform. The information found in this documentation refers only to the Hyperion security platform. Implementation of the security platform is optional. Hyperion strongly encourages using the security-platform authentication over the built-in modules authentication.
