OK, use this smb.conf. DO NOT CHANGE ANYTHING, DO NOT ADD ANYTHING.
This is based on what you have posted.
If WG isn't your workgroup, change it to your actual workgroup
If WG.LOCAL isn't your realm, change it to your actual realm
NOTE: if '.local' is your TLD, then turn off Avahi if it is running.
workgroup = WG
security = ADS
realm = WG.LOCAL
dedicated keytab file = /etc/krb5.keytab
kerberos method = secrets and keytab
server string = Samba 4 Client %h
log level = 10 vfs:1
idmap config * : backend = tdb
idmap config * : range = 2000-10000
idmap config WG : backend = ad
idmap config WG : schema_mode = rfc2307
idmap config WG : range = 500000-600000
winbind use default domain = yes
winbind nss info = rfc2307
winbind refresh tickets = yes
# user Administrator workaround, without it you are unable to set privileges
username map = /etc/samba/user.map
# For ACL support on domain member
vfs objects = acl_xattr
map acl inherit = Yes
store dos attributes = Yes
# Share Setting Globally
unix extensions = no
reset on zero vc = yes
veto files = /.bash_logout/.bash_profile/.bash_history/.bashrc/
hide unreadable = yes
max log size = 1000
syslog = 10
load printers = no
printing = bsd
show add printer wizard = no
disable spoolss = yes
printcap name = /dev/null
#======================= Share Definitions =======================
comment = File share

read only = no
Create the user.map referenced above.
!root = WG\Administrator WG\administrator Administrator administrator
Now create an LDIF on the DC, again change 'wg' and 'local' if required.
You will also probably need to change '500000' to the next free GID number in the
dn: CN=Domain Users,CN=Users,DC=wg,DC=local
msSFU30Name: Domain Users
Now add the gidNumber to Domain Users with:
ldbmodify -H /var/lib/samba/private/sam.ldb -U Administrator /tmp/DU.ldif
NOTE: you may have to install the ldb-tools package.
Back to the client and leave the domain:
First stop all Samba processes
net ads leave -U Administrator
Alter /etc/krb5.conf to just this:
default_realm = WG.LOCAL
dns_lookup_realm = false
dns_lookup_kdc = true
net ads join -U Administrator

The 'unwilling to perform error' is fairly common and can be ignored.
By setting the 'NIS DOMAIN' to 'all' , all you are doing is adding the
gidNumber for 'all' to the user, this doesn't affect the users primary
group, which windows and winbind expects to be 'Domain Users', this
means that 'Domain Users' must have a gidNumber, if 'Domain Users'
doesn't have a gidNumber, then ALL your users will be ignored by
If you later upgrade to Samba 4.6.x, you will be able to use the 'NIS
Domain as the users Unix primary group.
