Authentication data contains authentication credentials for OpenSSO Enterprise users. An authentication data store is aligned with a particular authentication module, and might include:
SafeWord authentication servers
RSA ACE/Server systems (supports SecurID authentication)
LDAP directory servers
Identity data may include authentication credentials although authentication data is generally stored in a separate authentication repository. For more information, see Chapter 3, Configuring Authentication, in Sun OpenSSO Enterprise 8.0 Administration Guide.
