The Master Access Point attribute contains the access point of
 the DSA which holds the master of this naming context. If
 the attribute has a value, then the naming context is a
 shadow naming context, that is, a naming context that has been
 replicated to this DSA. If the attribute has no value, then this
 DSA is the master DSA for the naming context.

 The Master Access Point attribute is read-only and single-valued.

 Syntax:
 	SHOW DSA NAMING CONTEXT <name> MASTER ACCESS POINT

 where <name> is the identifier of a Naming Context entity.
