How To Get an OID
Occasionally, an application being developed, a system configuration design, or other requirement you will have to add additional Attributes to an existing Object Class. You may even want or need to define a new Object Class. To do that, you will need to register these new schema elements with the Internet Assigned Numbers Authority (IANA). The IANA operates an online service you can use to get an Object ID (both attributes and object classes are considered “objects” needing a unique ID).
To get a unique Object ID for an Attribute or ObjectClass, please go to https://pen.iana.org/pen/PenApplication.page.
It is never appropriate to make up an OID or use someone else’s. They
are free and easy and your OID will be unique. That means that if you
ever have to use
back-ldap to connect to another directory
back-meta to create a virtual/meta directory, all the
OIDs will be unique.
