The rules for what data can be added or included in the database is theActive Directory schema. An example of a Class that is stored is the user class. Some exampleattributes of the user class might be the user’s first name, last name, phone number, and so on.Companies can extend the Active Directory database by adding their own unique Attributesand Classes to solve environment-specific needs. Dell™ has extended the schema to include thenecessary changes to support remote management Authentication and Authorization.Every Attribute or Class that is added to an existing Active Directory Schema must be definedwith a unique ID. To maintain unique IDs across the industry, Microsoft maintains a databaseof Active Directory Object Identifiers (OIDs) so that when companies add extensions to theschema, they can be guaranteed to be unique and not to conflict with each other. To extend theschema in Microsoft's Active Directory, Dell received unique OIDs, unique name extensions,and uniquely linked attribute IDs for our attributes and classes that are added into thedirectory service.Dell extension is: dellDell base OID is: 1.2.840.113556.1.8000.1280RAC LinkID range is:12070 to 12079The Active Directory OID database maintained by Microsoft can be viewed athttp://msdn.microsoft.com/certification/ADAcctInfo.asp by entering our extension Dell.
