Pulled straight out of my old user creation script, which I used with no 
issues for some time with multiple verisons of samba 4.1.x:

samba-tool user create $user --uid-number=$uid --gid-number=$gid --login-shell=/bin/bash --home-directory=/home/$user

(Later replaced with a script i found on the internet that created a new 
user without rfc2307 attributes, then used ldbmodify to automatically 
generate the unix uid based on the SID, much like winbind would do.)
