RE: OpenLDAP + Microsoft Outlook

[Simon Thornton <simon.thornton@swift.com>]

Hi,

The actual search string used by LDAP service in Outlook can be found in the registry and
looks like the following:

	(&(mail=*)(|(mail=%s*)(|(cn=%s*)(|(sn=%s*)(givenName=%s*)))))

This is located on my system (W2K) under:

HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows
Messaging Subsystem\Profiles\Microsoft Outlook Internet
Settings\a27d8e6a79dd0b489277326299b681de

Dunno if this is a common CSID amongst systems but try searching for the name of your LDAP
server and look for the above string.

By default the query isn't very efficient, a little tuning can improve performance
dramatically. As you observed it does generate a lot of traffic due to the multiple search
items.

You can always widen the search by inserting other filter statements. e.g.: To search the
telephoneNumber and postal address, you would change the search to:

(&(mail=*)(|(mail=%s*)(|(telephoneNumber=%s*)(|(postalAddress=%s*)(|(cn=
%s*)(|(sn=%s*)(givenName=%s*)))))))

Or, search the DN as well:

(&(mail=*)(|(mail=%s*)(|(dn=%s*)(|(cn=%s*)(|(sn=%s*)(givenName=%s*))))))


This string is set during installation in the file MAPISVC.INF, which is
under

	C:\Program Files\Common Files\System\Mapi\1033\NT

On my system, or part of the installation tree if you did an administrative install of
office to a file server.



Rgds,
