Another newbie question

[Bennett Samowich <brs@ben-tech.com>]

If I create a directory using one set of data (say... OC person) and then 
need to modify it later (say... adding OC organizationalPerson) can I just 
add the extra data to it?  If I understand the documentation I should have 
to turn the whole directory into ldiff format, change the 
schema/class/whatever, then reset the directory.

I'm asking so that I know how much I can adapt the directory as time 
progresses (e.g.  Manager asks can we put "this" in the directory?).

Thanks in advance,
- Bennett
