Oracle 11g XE - ORA-31202: DBMS_LDAP: LDAP client/server error: SSL handshake failed when connecting AD

Question

I'm trying to integrate my oracle 11g XE instance (version forced by product I'm working with) with Samba based Active Directory on port 636. Unfortunetally, I'm getting error ORA-31202: DBMS_LDAP: LDAP client/server error: SSL handshake failed. I've set oracle wallet, trying with openssl an keytool (using SE version), but it's not working with any of them. I've seen same problem here, but it was resolved by adding java procedure which is not supported by XE. If anybody could help me, I'd be really, really grateful. I'm storing my test procedure below, but it's nothing more than minimal required standard one:

declare
  l_retval varchar(100);
  p_session dbms_ldap.session;
  begin
  
    dbms_ldap.use_exception := true;
    p_session := dbms_ldap.init(hostname => 'myldaphost',
                                portnum  => 636);
                                
    l_retval := DBMS_LDAP.open_ssl (p_session,'file:/u01/app/wallet2',
                                    'xxxxx', 2);
                                
    l_retval := dbms_ldap.simple_bind_s(ld     => p_session,
                                   dn     => 'myuserdn',
                                   passwd => 'xxxxx');
  end;

#EDIT: That's why I've managed to capture with tshark:
