If people are prepared to use old programs such as these, then they are 
also probably using old OS versions and presumably will be prepared to 
use old versions of Samba.

I do not really know what you are planning, but if it has anything to do 
with SMBv1, then, in my opinion, it will be wasted effort, it is 
unlikely there will be anything modern that will talk SMBv1.

Yes, glue made from water and flour i.e. not a very good glue.

I know your feelings on on keeping the old ways working, but there comes 
a time when you have to accept that keeping some things going isn't 
worth the effort and can hold other things back.

We already are, there are some very weird ways of doing things turning 
up, things that had to be done that particular because they couldn't be 
done any other way at the time. Things that could now be done easier 
with AD.
