I’m sure this must work for someone, but I’m having a heck of a time with ADAM.  The latest is that I can create users just fine, assign properties to them, etc., but I cannot seem to set their passwords.  I feel like I’m missing something here, possible a permissions problem, although I can set passwords through the ADSI GUI.  The other possibility is that the user is not in the right state, maybe not correctly enabled, or something.  This is the code that should work

            entry = new DirectoryEntry("LDAP://localhost:50000/CN=test.user,OU=Users,C=Bank", null, null, AuthenticationTypes.Secure);


            entry.Options.PasswordEncoding = PasswordEncodingMethod.PasswordEncodingClear;

            entry.Options.PasswordPort = 50000;


            entry.Invoke("ChangePassword", new object[] {"old","new"});

Unfortunately, I have no idea what the problem really is, because all I get back is

System.Reflection.TargetInvocationException was unhandled
  Message="Exception has been thrown by the target of an invocation."
       at System.DirectoryServices.DirectoryEntry.Invoke(String methodName, Object[] args)
       at AdAzMan.Program.Main(String[] args) in Program.cs:line 43
       at System.AppDomain.nExecuteAssembly(Assembly assembly, String[] args)

       at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state)
       at System.Threading.ThreadHelper.ThreadStart()

Where the inner exception is {"An operations error occurred. (Exception from HRESULT: 0x80072020)"}.  Not very helpful.  That’s pretty much equivalent to “something bad happened”.  Granted, it’s a different error from the ones I get if the bind fails, or if I don’t set the entry’s password options to allow changing the password over an insecure channel, but this one’s got me stymied.
