In ADSI, refers to a COM object that
implements one or more interfaces.
In Active Directory®, the basic named unit of storage. A
directory object is an instance of an object class, which is
defined in the Active
Directory Schema.
object class
A formal definition of a specific kind of object that can be
stored in the directory. An object class is a distinct, named set
of attributes that represents something concrete, such as a user, a
printer, or an application. The terms object class and
class are used
interchangeably.
object class
instance
Represents a discreet occurrence of an object class.
object identifier
(OID)
A numeric value that unambiguously identifies an object class,
attribute, or syntax in a
directory service.
An OID is represented as a dotted decimal string (for example,
"1.2.3.4").
An operation is the interaction that a subject wants to have
with an object. For example, when a user (the subject), wants to
access (the operation), a given server (the object), over the
network, a policy determines whether that access will be
allowed.
operational
attribute
An attribute implemented internally by a particular directory
implementation. Operational attributes do not appear in the schema
and must be requested explicitly. Operational Attributes occurred
originally in the X.500 specifications for a directory service and
have been carried over into the LDAP version 3 specifications (RFC
2251). RFC 2251 requires support for certain operational
attributes; a given directory implementation may implement any
number of others.
