The Anonymous authentication module allows a user to log in to OpenSSO Enterprise without specifying validating credentials. Anonymous connections are usually customized by the OpenSSO Enterprise administrator so that Anonymous users have limited access to the server (for example, access for read or access for search), or to specific trees or entries within the identity data store. A list of anonymous users can be defined by adding the applicable user identifier(s) to the module's Valid Anonymous Users attribute. Granting anonymous access means that it can be accessed without providing a password. A default anonymous user is created during OpenSSO Enterprise installation. For information on the Anonymous authentication module attributes, see Anonymous in Sun OpenSSO Enterprise 8.0 Administration Reference.
