Object identifier (OID)

An object identifier (OID) is a string of decimal numbers that uniquely identifies an object. These objects are typically an object class or an attribute.

These numbers can be obtained from the IANA (Internet Assigned Number Authority). The IANA website is at: http://www.iana.org/iana/

If you do not have an OID, you can specify the object class or attribute name that is appended with -oid. For example, if you create the attribute tempID, you can specify the OID as tempID-oid.
