InetOrgPerson Accounts
Active Directory provides support for the InetOrgPerson object class and
its associated attributes defined in RFC 2798. The InetOrgPerson object
class is used in several non-Microsoft LDAP and X.500 directory services
to represent people within an organization.
Support for InetOrgPerson makes migrations from other LDAP directories to
Active Directory more efficient. The InetOrgPerson object is derived from
the user class and can be used as a security principal just like the user
class. For information about creating an inetOrgPerson user account, see
Create a new user account .
When the domain functional level has been set to Windows Server 2003, you
can set the userPassword attribute on InetOrgPerson and user objects as
being the effective password just like you can with the unicodePwd
attribute.

forest. The MsmqServices object is of the MSMQ-Enterprise class type. The
MsmqServices object contains organization-wide configuration information
for Message Queuing.
