Managing Users
Just as Linux and Windows have defined user accounts that determine which users have logon privileges, MDS also has user accounts that define who can access the MDS repository.
In MDS, you need to understand the difference between the following:
The Database user is the Teradata login used by MDS to connect to the repository database. That login is identified by the user name and password set in the MDS Database Configuration.
The MDS default Administrator is created when the MDS repository is created. Other MDS Administrators can be created by an MDS Administrator using Teradata MDS.
The MDS default Administrator user name is metasu. The default password for the MDS Administrator is also metasu.
Note: You cannot change the MDS Administrator user name, it is always metasu.
To maintain the integrity of the system, it is recommended that you change the MDS Administrator password immediately after the installation. You can also change the password when running metacreate by specifying the -m parameter. This is an ideal time for limiting superuser access to the repository.
MDS Users are added later by the MDS Administrator using Teradata MDS. The MDS Administrator is responsible for adding other MDS users through the MDS MetaManager dialog box.
MDS users created without MDS Administrator privileges are non-administrators. Their access to data in the MDS repository database is based on ownership and permissions of the objects in the MDS repository database, which is set using security profiles. These users can be assigned to security profiles with different levels of access permission.
An MDS user name and password is required to connect to the MDS repository. When connected, the metadata objects that can be viewed or modified by the user are determined by the permissions in the security profile assigned to each metadata object stored in the MDS repository. For more information on security profiles see “Security Profiles” on page 67.
If a specific object is requested and the user does not have permissions, a permission error is returned. If a collection of objects is requested, MDS will return only the objects that the user has permission to access.
