I think I have all the settings configured properly, plus it works with
4.16, but not 4.17.  4.17 is working for Christian though.

smb.conf

[global]
    security = ads
    workgroup = EXAMPLEAD
    realm = AD.EXAMPLE.COM
    local master = no
    idmap config *:backend = tdb
    idmap config *:range = 100000-199999
    idmap config EXAMPLEAD:backend = ad
    idmap config EXAMPLEAD:schema_mode = rfc2307
    idmap config EXAMPLEAD:range = 512-99999
    idmap config EXAMPLEAD:unix_nss_info = yes
    idmap config EXAMPLEAD:unix_primary_group = yes
    winbind use default domain = yes
    winbind refresh tickets = yes
    winbind offline logon = yes
    winbind nss info = rfc2307
    kerberos method = system keytab
    dedicated keytab file = /etc/krb5.keytab
    create krb5 conf = no
    map to guest = Bad User


samba-tool user show dale
  primaryGroupID: 513
  uid: dale
  uidNumber: 10000
  gidNumber: 513

samba-tool group show "Domain Users"
  gidNumber: 513


Thanks,
