You should only have:

Domain Admins
Enterprise Admins

You definitely shouldn't have Domain Users, this make ALL your domain
users into admins and I don't think you want that ;-)

Do you actually need the keytab ? It is only required if something like
Dovecot needs to auth to AD.

If you do need the keytab, you can create it with samba-tool:

samba-tool domain exportkeytab

This will create a keytab with all the keytabs in it, if you just want
one keytab, add '--principal=PRINCIPAL'.

Add '--help' to the command above for more info
