# TWikiUserMappingContrib %SHORTDESCRIPTION%
The _User Mapping Manager_ interface provides services for mapping between a 'user identity' as used when talking to an external authentication provider, an internal TWiki canonical user ID, and the displayed name used to identify the user in TWiki. This is the default TWikiUserMapping in which user information is stored in TWiki topics - one per user, and then any mapping needed is done using the TWikiUsers topic in the Main. see [SimplifiedUserMappingCodeInterface](http://twiki.org/cgi-bin/view/Codev/SimplifiedUserMappingCodeInterface) on TWiki.org for a more detailed discussion of the concepts. It includes the topics that are used when registering and managing users and groups via TWiki, in [[TWikiTopics]]. it includes: - Registration and user management topics - [[TWikiRegistration]] - [[ResetPassword]] - [[ChangePassword]] - [[ChangeEmailAddress]] - [[BulkRegistration]] - [[BulkResetPassword]] - Documentation topics - [[ManagingUsers]] - [[UserToolsCategory]] - [[LoginName]] - default groups and user - [[NobodyGroup]] - [[TWikiAdminGroup]] - [[TWikiRegistrationAgent]] - User lists - [[UserList]] - [[UserListHeader]] - [[UserListByDateJoined]] - [[UserListByLocation]] - [[UserListByPhotograph]] - User and Group template files - [[NewUserTemplate]] - [[UserForm]] - [[TWikiUsersTemplate]] - [[UserHomepageHeader]] - [[TWikiUserSetting]] - [[TWikiGroupTemplate]] If you are developing a non-TWiki based User mapper, you might like to consider removeing or replacing the files installed by this Contrib. ## Settings The [[TWikiUserMappingContrib]] specific settings have not yet been moved out of the standard TWiki.spec. This will be done in a future release. ## Installation Instructions It's a part of the default distribution of the TWiki Core. ## Contrib Info
