Hardly suddenly, we have been discussing this on here for a couple of 
years now, also this is being forced on us by Microsoft. They really 
want to get away from SMBv1, so Samba must follow them and you must have 
SMBv1 for an NT4-style domain. However, for the moment, you can still 
use NT4-style domains, Samba is just giving warning that they will 
disappear one day and when that day comes, I understand that the last 
version that does work with them will have long term security support.

Yes this probably will be possible, what do have in ldap ?

Pretty much like openldap, have a look here:
