You have problems, mainly because you are using Centos 8 with a version 
of Samba >= 4.8.0.

You cannot use sssd with Samba >= 4.8.0, you must use winbind, but even 
if you use winbind (which incidently you are), you cannot kerberos with 
PAM because red-hat removed the required package.

How fixed are you on using Centos ?

Are you prepared to use a different distro ?
