Java Security

Hi,
I am trying to establishing SSL from Java Application(via Netscape Directory SDK 4.0 - Java version) to the Directory Server(ADS) in a secure manner - i.e. LDAP over SSL.

I am trying to run this code...

LDAPConnection ld = null;
LDAPModificationSet attrs = new LDAPModificationSet();
attrs.add(LDAPModification.REPLACE,new LDAPAttribute("unicodePwd", "testpassword"));

try
{
LDAPSSLSocketFactory ssl = new LDAPSSLSocketFactory();
ld = new LDAPConnection( ssl );

/* Connect to server */
ld.connect("10.10.10.7",636);

/* Authenticate to the server as directory manager */
ld.authenticate(adminDN,password);

/* Now modify the entry in the directory */
ld.modify( userDN, attrs );
}
catch(Exception e)
{}


But I don't know where my program reads the Cert. info... I don't know
if I have to import my internal CA via keytool or I have missed some
special configuration ..

When I run this code, the following error appears:

netscape.ldap.LDAPException: Failed to create SSL socket (91); Cannot connect to the LDAP server

Is this possible? If so, what hints can you give me to get started (any sample code would be greatly appreciated).

Thanks in advance.
