RE: Extending the schema: What about OIDs?
Adam,
As we are using the core schema and extending it few more attributes, do we
need to get OID specifically for these additional attributes? Is that what
you are saying?
My understanding is that we need to get an OID if the schema is totally new
and independent of core schema. Correct me if I am wrong.
Thanks,

We have not begun to gain freedom from error, the freedom that comes from
the right reason. We have not begun to gain freedom from hate, the freedom
that is born of love. Thats the true meaning of our wars.

They are defined by the same authority. The OID should remain the same.

As well it should.

Go to IANA's web site.

"IF"! If you define schema you need your *OWN* OID.

No, do not adjust existing schema, those are the OIDs of that schema,
defined by people with authority to use that OID.
I have a section on OIDs in my LDAP presentation -
