You should not use SSL, but startTLS.
Using SSL in LDPA has been deprecated. Not that it does not work, but
it's not the way to secure your connection to the server, as it requires
a second port.
Doing something like :
LdapConnectionConfig tlsConfig = new LdapConnectionConfig();
tlsConfig.setLdapHost( ... );
tlsConfig.setLdapPort( ... );
tlsConfig.setTrustManagers( <your TrustManager> );
connection = new LdapNetworkConnection( tlsConfig );
connection.connect();
connection.startTls();
connection.bind( ... );
is the correct way to connect to a LDAP server.
