scheme extension with own OID

Hi list,

Because of a concern to modify our ldap environment I need to extend the scheme. The attribute I need is vacationActive and some other attributes which I didn't find in the existing OpenLDAP schemes.

My question to you is, if I need to get a registered OID for our company to define the objectclass "vacation" with some further attributes? -I have read some articles about this-

Or is there an up to date OID-list where I can search for a vacation objectclass or the vacation attributes which maybe already exist?

- I only found the following -

Any hints would be very appreciated.

Thanks in advance.

Kind regards.

Andreas
