Essbase user management and security is provided through EPM System security, which uses Oracle Hyperion Shared Services to provide user management, user provisioning, and external authentication definition. Provisioning refers to the process of assigning roles and access permissions to users for Essbase applications.
Products that implement EPM System security require access to a Shared Services server running Shared Services client and server software, and to a database dedicated to Shared Services.
When using the default deployment option, Essbase is deployed in EPM System security mode.
If you choose not to deploy Essbase in EPM System security mode, Essbase uses its own native security mode to manage security for Essbase applications, databases, and artifacts. There is no change in behavior for Essbase in native security mode, except when using native security mode with external authentication. See Continuing to Use Essbase in Native Security Mode.
To use EPM System security for Essbase deployments that are in Essbase native security mode, you must migrate any Essbase Server applications and any existing Essbase users and groups to Shared Services. See Migrating Essbase to EPM System Security.
