title: LDAPException(resultCode=91 (connect error), errorMessage='An error occurred while attempting to connect to server
body: <p>I am tring to make an android app to connect at an LDAP server. I am using UnboundId library so my app to be able to establish an LDAP connection. The problem is the resultCode 91-connection error and I don't know how to resolve it. The LDAP server is up and running because my desktop app can establish a connection.
   I will attach the code:</p>
  
  <pre><code>           TextView tv = (TextView)findViewById(R.id.textView);
       try {
          LDAPConnection c = new LDAPConnection("192.168.106.131",389,"cn=admin,dc=test,dc=com","haha");
  
          if(c.isConnected())
          {
              tv.setText("good");
          }
          else
          {
              tv.setText("bad");
          }
      } catch (LDAPException e) {
          tv.setText("error");
          e.printStackTrace();
      }
  </code></pre>
  
  <p>And the log from LogCat:</p>
