If I enable the PAM plugin of 389-ds, I'm able to let users be 
authenticated by PAM, even if the user is not present il LDAP, hence the 
plain-text password is passed to PAM.
The only missing step is: if PAM correctly authenticates a non-existing 
user, it should be created (using the just supplied password).
