Your REALM MUST be the DNS domain in uppercase.
Your workgroup CANNOT be the same as your REALM.

If you are going to set the above, you also need to add:
dedicated keytab file = /etc/krb5.keytab

You should let Samba find the 'password server', so remove the line

You are using the same ranges for both domains, this is not allowed,
also you really should start from a different number than '1000'
The 'ACME.DOM' should be the workgroup.

Once everything is working okay, remove the two lines above.

Remove the 'ldap' lines they are not used on a Unix domain member and
if they are correct, your REALM should be 'ACME.DK'

No, you don't use wins with active directory.

What is in '/etc/samba/smb.conf.%h' ?
