[Samba] hosts allow option is not applaying without restart smbd

[L.P.H. van Belle]

Hai, 

As Harald showed, this is a known thing, this did hit samba, after the multi threaded support. 
See also : systemctl cat smbd.service 
For what works what not. 

For a reload the kill -HUP MAINPID is, as i know, the only thing that works atm. 

Is this a AD DC  or a member? ( sorry didnt follow the complet thread ) this catch my eye just now. 
Imo, for a member it should work, but i've not tried it. 


Greetz, 

Louis
