LDAP confusion using Edirectory

Good morning,

I am trying to set up my openfire server to use LDAP with our edirectory, however almost all of our users are listed in the groups, not in the users.

No doubt that this stems from my LDAP newbieness, but as I understand my tree:

Sprechman

|->NMB

|->users

for the base DN I should use:

ou=users, ou=nmb, o=sprechman

is that correct?
