LDAP Addressbooks for multiple domains on one system

[Forrest Aldrich <forrie@forrie.com>]

I'm interested in setting up LDAP services to support multiple addressbooks 
(and possibly other services) for a system which hosts multiple/virtual 
domains.

From an organizational point of view, how might this best be 
accomplished/designed.

The goal being to plan out the organizational structure of the directory 
ahead of time.

I've looked around the net and have found various articles about planning 
out a general addressbook, but nothing I've seen really discusses this 
scenario.   I saw reference to ldapv3 feature of something like dn=My 
Name+domain.name as an added flag.  But not sure if that is really where 
this should go.


Thanks,
Forrest
