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 - 
Ximian GNOME, Evolution, LTSP, and RedHat Linux + LVM & XFS
