LDAP Feature for the RCSxxx | xxx107
Attributes
There is one more hierarchy used in AD. Associated with each object class is a
set of “attributes” used to store specific information about the entity that is
being represented. For example, associated with the User object class is an
attribute type named SAM ACCOUNT NAME and others such as FIRST
NAME, SURNAME, PASSWORD, etc. The suite of Dell Remote Console
Switches uses the SAM ACCOUNT NAME and PASSWORD attributes to
authenticate a user (the formal AD names for these two attributes are
sAMAccountName and unicodePWD, respectively).
Schema Extensions
AD is packaged with many object classes, including default containers for
Computer and User objects as well as classes for OU containers and classes to
represent computer and user entities. AD can be extended to include new object
classes such as those provided by Dell to simplify the administration of access
controls; such extensions are usually referred to as “schema extensions” and are
at the heart of the Dell Extended Schema feature described in this document.
These schema extensions provide customized object classes to represent Dell
RCSs, access control information, and a type of container used to associate
specific access control information with specific instances of Dell RCSs and
Users. It is important to note that each attribute type and object class used in
AD must have a globally unique identifier, known as an Object Identifier (OID).
These unique identifiers are ultimately managed by internationally recognized
authorities. For AD, the OID space is managed secondarily by Microsoft. Dell
has obtained OIDs for the custom object classes and attribute types used in the
Dell Extended Schema feature. The following is a summary of the OIDs Dell
obtained:
Dell extension is: dell
Dell base OID is: 1.2.840.113556.1.8000.1280
RCS LinkID range is: 12070 to 12079
