Users are entities that can be authenticated in a security realm. A user can be a person, such as application end user, or a software entity, such as a client application, or other instances of a WebLogic Server. As a result of authentication, a user is assigned an identity, or principal. Each user is given a unique identity within the security realm. Users may be placed into groups that are associated with security roles, or can be directly associated with security roles.
Groups are logically ordered sets of users. Users are organized into groups that can have different levels of access to WebLogic resources, depending on their job functions. Managing groups is more efficient than managing large numbers of users individually. All user names and groups must be unique within a security realm.
Note: The instructions for the using the Administration Console apply to users and groups in the WebLogic Authentication provider only. If you customize the default security configuration to use a custom Authentication provider, use the administration tools supplied by that security provider to create a user. If you are upgrading to the WebLogic Authentication provider, you can load existing users and groups into its database. For more information, see Migrating Security Data
