How to retrieve DirectoryEntry from a DirectoryEntry and a DN
14,536
DirectoryEntry User = YourPreExistingUser();
string managerDN = User.Properties["manager"][0].ToString();
// Browse up the object hierarchy using DirectoryEntry.Parent looking for the
// domain root (domainDNS) object starting from the existing user.
DirectoryEntry DomainRoot = User;
do
{
DomainRoot = DomainRoot.Parent;
}
while (DomainRoot.SchemaClassName != "domainDNS");
// Use the domain root object we found as the search root for a DirectorySearcher
// and search for the manager's distinguished name.
using (DirectorySearcher Search = new DirectorySearcher())
{
Search.SearchRoot = DomainRoot;
Search.Filter = "(&(distinguishedName=" + managerDN + "))";
SearchResult Result = Search.FindOne();
if (Result != null)
{
DirectoryEntry Manager = Result.GetDirectoryEntry();
}
}

I have a
DirectoryEntry
object representing a user. From theDirectoryEntry.Properties
collection, I am retrieving the"manager"
property, which will give me a Distinguished Name ("DN") value for the user's manager.Can I retrieve a
DirectoryEntry
object for the manager from just these two objects? If so, how?I'm envisioning something like
DirectoryEntry.GetEntryFromDN(dnManager);
, but I cannot find a similar call.Just to clarify, the DirectoryEntry and DN are the only pieces of information I have. I cannot instantiate a new
DirectoryEntry
because then I would have have to either use the default Directory and credentials or have the Directory name/port and username/password. -

DirectoryEntry
with the default Directory only; I need to account for the Directory not using the machine's default directory. It also looks like you're assuming that I can statically provide the credentials to connect. -
palswim almost 13 yearsI would rather not traverse the directory tree myself or construct a search query, but it looks like this is the best answer for now.

Onno about 8 yearsIt might not be the quickest way ( it seems a tad slow on my machine) but it really helped me for a quick fix. Thnx :)
