How to use 'Base Dn' in DirectorySearcher Filter?

[Dave]

I'm using ldp.exe to connect to our global catalog in order to test my ad
search:

Base Dn: dc=abc,dc=mycompany,dc=com
Filter: (&(sAMAccountName=jsmith))
Scope: SubTree

Works fine, but how do I incorporate the 'Base Dn' attribute in the
DirectorySearcher below?

Here's my code:

DirectoryEntry entry = new DirectoryEntry("GC://mycompany.com", user, pass);
DirectorySearcher search = new DirectorySearcher(entry);

search.Filter = "(&(sAMAccountName=jsmith))";;
search.SearchScope = SearchScope.Subtree;
SearchResult result = search.FindOne();

Where does the Base Dn fit above? Thanks

The DirectorySearcher gets both the Base DN and the credentials used for
binding from the DirectoryEntry object that is set in the SearchRoot
property.

In your code below, to set the base DN, add that DN to the ADsPath in the
first argument of your DirectoryEntry constructor:

DirectoryEntry entry = new DirectoryEntry
("GC://mycompany.com/dc=abc,dc=mycompany,dc=com", user, pass,
AuthenticationTypes.Secure);

The ADsPath is essentially composed of the scheme, the server information
(which is optional with AD sometimes) and the object name, which with LDAP
(or GC), is the DN of the object.

HTH,
