How do I clear out a user object attribute in Active Directory?

Question

Suppose you have connected to Active Directory using the simple syntax:

string adPath = \"LDAP://server.domain.com/CN=John,CN=Users,dc=domain,dc=com\";
Direc         


        

Answer 1

Not sure that you can delete it since user objects usually follow a company schema but maybe something like the following will work:

userEntry.Properties["mail"] = null;

or maybe:

userEntry.Invoke("Put", "mail", null); 

then:

userEntry.CommitChanges();

Answer 2

It turns out to be pretty simple, albeit not very commonly used...

string adPath = "LDAP://server.domain.com/CN=John,CN=Users,dc=domain,dc=com";
DirectoryEntry userEntry = Settings.GetADEntry(adPath);
userentry.Properties["mail"].Clear();
userentry.CommitChanges();
