[Samba] samba3 authentication from samba4 active directory

[I Am Netizen]

Hello,

Can we authenticate user accessing samba3 shared folder against samba4
active directory?

Consider this case:

I have 2 instance; one is samba4 and other one is old samba3 which has few
shared folder.
I want user accessing samba3 shared folder should authenticate again samba4
active directory?

How we can do this?
