For a start, you are running an version of Samba that is EOL, you should 

You are also using sssd for authentication and asking here for help, 
Samba does not produce sssd and as such, we know little about it, you 
will get better help on the sssd-users mailing list, though I think they 
will probably advise doing the same thing as I am advising about Samba, 

There is a problem though, if you upgrade to a supported Samba version 
and require shares, you cannot use sssd, you must use winbind.
