Re: Attribute Syntax

["David Smith" <DavidSmith@byu.net>]

You could create a new objectClass that stores attributes that you are
interested in: address, phone, state, etc. Then, create several entries
based on that objectClass as *children* of the desired entry. So, to use
your vernacular, each child entry is like a struct, hashable based on one
(or more) of its attributes.

So, like this:

dc=example,dc=com
   ou=People
      cn=Dave Smith
         cn=address1
         cn=address2
         cn=address3
      cn=Bob Jones
         cn=address1
         cn=address2
     ...

The sub-entries would look like this:

dn: cn=address1,cn=Dave Smith,ou=People,dc=example,dc=com
name: police
phone: 911

dn: cn=address2,cn=Dave Smith,ou=People,dc=example,dc=com
name: fire
phone: 555-1234

etc...

The search filter would be easy too. Just use

(name=fire) with a search base of cn=Dave Smith,ou=People,dc=example,dc=com

This may be slightly unorthodox, but similar to the nsliProfileName idea.
I think it would be pretty cool. Let us know what you decide to do.

Just my 2 cents
