What type of object class is sambaSamAccount?

A structural object class defines the primary characteristics of an entry and determines what kind of entry it can be (e.g., `person`, `organization`); `sambaSamAccount` is not a primary entry type.

`sambaSamAccount` is an auxiliary object class because it extends existing entries (like `inetOrgPerson`) with additional Samba-specific attributes without requiring them to be of a completely new structural type. Auxiliary object classes are added to existing entries to provide additional characteristics.

An abstract object class cannot be instantiated directly; it serves as a template or superclass for other object classes, and `sambaSamAccount` is instantiable.

"Extended" is not a standard type of object class in LDAP schema definitions; the main types are structural, auxiliary, and abstract.
