A global user is a repository user who is found in all members of a repository federation and whose attribute values are the same in all of the repositories. Global users are managed through the governing repository. If you add a global user to the governing repository, that user is added to all the member repositories by a federation job that synchronizes the repositories.
To create a global user, connect to the governing repository of a federation and create the user there. On the New User - Info page, select User is global to make the user global. Use the instructions in Creating or modifying users to create the user.
Connect to the governing repository to modify the attributes of a global user.
Global users can also have local attributes, which you can modify in a local repository.
