LDAD over SSL Error on a Server

Kozela asked
Last Modified: 2013-12-24
Hello Everyone,

I was wondering if someone can help me solve this riddle.  I need to authenticate a user against LDAP over SSL.  I have written the following method:

 public static bool UserAuthetication(string userName, string password, string domain)
  bool authentic = false;
        DirectoryEntry entry = new DirectoryEntry("LDAP://" + domain, userName, password,  AuthenticationTypes.SecureSocketsLayer | AuthenticationTypes.Secure);
                object nativeObject = entry.NativeObject;
                authentic = true;
  catch (Exception e)
        authentic = false;
        return authentic;
        return authentic;


The method is called from the code as follows:
UserAuthetication("myUser", "myPassW", "rootDSE");

So here is my problem.  The mehod works correctly from multiple Workstations.  However, this code runs on a server and the code errors out everytime I run it on the server.  The code is used t authenticate an incoming request on a server.  I am guessing it has to do with the SSL certificates on the server but I am not sure where to start looking or which certificate it could be.  

Any ideas?
