LDAP over SSL help

[Marta]

Hi all,
I am trying to establish SSL connection from Java Application(via
Netscape Directory SDK 4.0 - Java version)

Here is my code...
{
.
.

LDAPConnection ld = null;
try{
sfactory = new LDAPSSLSocketFactory ();
ld = new LDAPConnection(sfactory);

ld.connecthost , 636,"uid="+name+ dn,password);
}

catch(Exception e)
{e.printStackTrace();}
.
.
}
this is my Classpath

C:\j2sdk1.4\lib\dt.jar;C:\jdk1.3.1\lib\ldapSDK.jar;C:\jdk1.3.1\lib\java40.jar;C:\jdk1.3.1\lib\ldap40.jar;C:\LDAP\lib\jcert.jar;C:\LDAP\lib\jndi.jar;C:\LDAP\lib\jnet.jar;C:\LDAP\lib\ldapbp.jar;C:\LDAP\lib\providerutil.jar;C:\LDAP\lib\ldap.jar;C:\LDAP\lib\jsse.jar;%CLASSPATH%

I tried to use this too
sfactory = new LDAPSSLSocketFactory
("com.sun.net.ssl.internal.ssl.SSLSocketImpl");

But in both cases when I run this code, the following error appears:

netscape.ldap.LDAPException: Failed to create SSL socket (91); Cannot

What is happen? what hints can you give me to get started
(any sample code would be greatly appreciated).

Thanks in advance.
