Re: Problem with LDAP query to resolve Email-address in C# app.

Hello,

using a query based on the purportedSearch is not a good thing (see http://www.infinitec.de/articles/exchange/getgal.aspx).

Another thing is, that you must do a search on the global catalog to get all addresses.

From within a the domain, do a bind on GC:

Then enumerate the childs of that object and take the first one. This object can be used as searchroot to search the entire forest.

Best regards,

Hello,
i try to create a function with a behavior like the Outlook or OWA
Ctrl-K.

My Organization have a primary domain controller and 5 child domain.

We have and Exchange Server on the primary domain e 5 child exchange
server in the 5 child domain.

I log in my primary domain controller with domain admin privilege.

I create a c# code like this:

DirectoryEntry entry = new
DirectoryEntry("LDAP://MyEchange.MyDomain.Com";);
DirectorySearcher searcher = new DirectorySearcher(entry);
searcher.SearchScope=SearchScope.Subtree.
searcher.filter="(& (mailnickname=*) (|
(&(objectCategory=person)(objectClass=user)(!(homeMDB=*))(!(msExchHomeServerName=*)))(&(objectCategory=person)(objectClass=user)(|(homeMDB=*)(msExchHomeServerName=*)))(&(objectCategory=person)(objectClass=contact))(objectCategory=group)(objectCategory=publicFolder)(objectCategory=msExchDynamicDistributionList)
))";

I retrieve the query for the filter from the purportedSearch in the
Default Global Address List with ADSI edit.

My Problem is that the addresses i retrieve with this query is not the
same of the Exchange System Manager preview on the Default Global
Address List.

In the Exchange System Manager i retrieve(obviously) all the addresses
of my organization with all child domain addresses.

With my query i have only the addresses and contact(and public folder)
about the addresses in the primary domain controller but i can't
retrieve the child domain addresses.

If i copy my query on a custom query in Active Directory Users and
Computer in the same server (MyExchange.MyDomain.Com) I retrieve the
addresses of my query and not the same of the Exchange System Manager.

I think is an Entry Point Problem?

Can anyone help me please?


Thank,Alessandro.
