See my modifications:

  default_realm = DOMAIN.LOCAL
  dns_lookup_realm = false
  dns_lookup_kdc = true

That is all you need in krb5.conf

  workgroup = DOMAIN
  security = ADS
  realm = DOMAIN.LOCAL

  idmap config *:backend = tdb
  idmap config *:range = 5000-9999
  idmap config DOMAIN:backend = rid
  idmap config DOMAIN:range = 10000-999999

  winbind trusted domains only = no
  winbind use default domain = yes
  winbind refresh tickets = yes
  template shell = /bin/bash
  template homedir = /home/%D/%U
