I will say this again, just because 'wbinfo -u' shows the users in AD,
this DOESN'T mean the underlying Unix OS knows who they are.

This is my smb.conf:

[global]
        netbios name = DC1
        realm = SAMDOM.EXAMPLE.COM
        server services = s3fs, rpc, nbt, wrepl, ldap, cldap, kdc, drepl, winbindd, ntp_signd, kcc, dnsupdate
        workgroup = SAMDOM
        server role = active directory domain controller
        idmap_ldb:use rfc2307 = yes
        load printers = no
        printing = bsd
        printcap name = /dev/null
        disable spoolss = yes
        tls enabled  = yes
        tls keyfile  = tls/DCKey.pem
        tls certfile = tls/DCCert.pem
        tls cafile   =
        template shell = /bin/bash
        template homedir = /home/%U
        winbind enum users = yes
        winbind enum groups = yes
        log level = 0
        ldap server require strong auth = allow_sasl_over_tls

[netlogon]
        path = /usr/local/samba/var/locks/sysvol/samdom.example.com/scripts
        read only = No

[sysvol]
        path = /usr/local/samba/var/locks/sysvol
        read only = No


I use Devuan with a self compiled Samba and these are the links I
create:

ln -s /usr/local/samba/lib/libnss_wins.so.2 /lib/x86_64-linux-gnu/libnss_wins.so
ln -s /usr/local/samba/lib/libnss_wins.so.2 /lib/x86_64-linux-gnu/libnss_wins.so.2

ln -s /usr/local/samba/lib/libnss_winbind.so.2 /lib/x86_64-linux-gnu/libnss_winbind.so
ln -s /usr/local/samba/lib/libnss_winbind.so.2 /lib/x86_64-linux-gnu/libnss_winbind.so.2

ln
-s /usr/local/samba/lib/security/pam_winbind.so /lib/x86_64-linux-gnu/security/pam_winbind.so

I would also suggest you check how PAM is setup.
