Unable to connect to OpenLDAP over SSL

Hi,

I am using Netscape LDAP Java SDK 4.1. I am trying to connect to online OpenLDAP server running over SSL. LDAP Browser is successfully connected to the OpenLDAP server over SSL. But every time when I run my own code I get the following error.

netscape.ldap.LDAPException: SSL connection to ldap.openldap.org:636 (91); Cannot connect to the LDAP server
        at netscape.ldap.factory.JSSESocketFactory.makeSocket(JSSESocketFactory.java:86)
        at netscape.ldap.LDAPConnSetupMgr.connectServer(LDAPConnSetupMgr.java:411)
        at netscape.ldap.LDAPConnSetupMgr.openSerial(LDAPConnSetupMgr.java:343)
        at netscape.ldap.LDAPConnSetupMgr.connect(LDAPConnSetupMgr.java:237)
        at netscape.ldap.LDAPConnSetupMgr.openConnection(LDAPConnSetupMgr.java:163)
        at netscape.ldap.LDAPConnection.connect(LDAPConnection.java:1033)
        at netscape.ldap.LDAPConnection.connect(LDAPConnection.java:915)
        at netscape.ldap.LDAPConnection.connect(LDAPConnection.java:759)
        at LDAPConnector.connect(LDAPConnector.java:20)

Here is my source code:

LDAPConnection m_ldpCon;

      System.out.println("Creating LDAPS Connection");
      JSSESocketFactory obj_jsseSocketFactory = new JSSESocketFactory(null);
      m_ldpCon = new LDAPConnection(obj_jsseSocketFactory);

m_ldpCon.connect("ldap.openldap.org", 636);

Plz help me to get rid of this error ...?

Regards,
