[Samba] Setting password in AD according to NT4 domain LDAP

[Michal67M at seznam.cz]

   Hi,
 
  is it possible to set password for user in AD,  if I  know its encrypted 
form (sambaNTPassword, userPassword) from NT4 domain LDAP? I need to copy 
users from NT4 domain to samba4 AD. 
  We'd like to move from samba NT4 domain to samba AD, but not with 
classicupgrade and we do not want to force users to change their passwords.

  Thanks, Michal
