There are at least 2 types of address books in Outlook: 'MAPI' and 'LDAP'.

In 'Cont_Name' I have sequentially receiving 2 names of address books:
- 'Outlook address book' (standart)
- 'name of my LDAP address book'

Then I receive valid number of folders in 'Outlook address book' and all
contacts in they (not in this code).
This part is working good.

And I can't receive any item in 'Hierarchy' or 'Contents' tables of 'LDAP
address book'.
Received contained items count is 0 (zero) in both cases.
Why ?
How can I read 'LDAP'-type Outlook address book contents programmatically ?
My 'LDAP'-connection contain several contacts, sure !
And I see them in Outlook.

LDAP address book provider does not display anythign in the contents table,
it only lets you search and displays the search results.
You can onserver this behavior in the Outlook UI.
This has to do with the fact that very few LDAP servers supports windowing
extensions (that allow to retrieve only a subset of entries) and retrieving
a large number (thousands) of entries is very expensive.
