Which schema to use?

[Nick Bright <nick.bright@valnet.net>]

Are there any pre-defined schema (or combination of schema) available 
that I could use with openldap that would provide some or all these 
attributes:

accountid (integer)
customerid (integer)
nodeid (integer)
accounttype (string)
accesspoint (string)
ipaddress (ip address)
latitude (float)
longitude (float)
macaddress (string)

A link to a novice/beginner guide for how to create schema would be 
helpful too.

Thanks,

--
