This option is used to check the metadata of the specified attribute for an object across all Domain Controllers in the domain.  This is a multi-threaded function to speed up the return of the results.  Each line represents the metadata for the attribute on the corresponding domain controller as specified by the Server column.  This option is perfect for checking that an attribute has been replicated across all the domain controllers.

The DN field is the DN of the object, and Attribute field is the name of the attribute to be checked.  This option can only check a single attribute at a time.
