OK, easy part first :-)

As the log says "idmap uid" & "idmap gid" are deprecated. You need to 
use "idmap config * : backend" instead, for an example see the member 
server page in the samba wiki: 
https://wiki.samba.org/index.php/Setup_a_Samba_AD_Member_Server

Not sure if this will cure your main problem, it probably won't, but 
start with the obvious first.
