Super-User Access
The user metasu is the administrative id created by MDS. The user metasu has full access to all objects in the MDS repository. The password for metasu should be a well kept secret, for use only by system administrators.
Any user in the repository can be granted superuser status if it is created by calling CMetaUser::CreateSuperuser. Granting superuser status to a user gives the user full access to all objects in the MDS repository. For that reason, system administrators should be careful about which users have superuser status, and the passwords for those users should be protected.
