Active Directory object selection for ASP.net 2

[Guest]

Hi,
I am looking for an Active Directory object selection for ASP.net 2.
My ASP.net page has a text field to enter a user's or computer's LDAP path
directly.
And a "Find..." button that shall display an Active Directory search GUI
like the dialog shown on a Windows Server 2003 under "Active Directory Users
and Computers - Find...".
I could not find an ASP.net server control for this.
I know that I can search the Active Directory using DirectorySearcher, but
how can I get the search user interface on the client side?
Any idea how this can be done?

Thanks and best regards, Matt
