[Samba] Windows pre-requisites for login with winbind?

I think we're getting confused with the kerberos issue created by my errant DNS server... with the original problem, all the commands I have sent showing an issue with kerberos were working originally, with the config which explicitly defined "kdc =", and are now working again, with your new config, now that I have fixed the DNS... but the original problem is that I have a very small number of users which don't work.... winbind says that they don't exist, while every other user works just fine... 

Those 3 users that don't work are the most recent 3 to be added, and since I don't have control over the AD, I can't say if there's some parameter or group they don't have which stops them from working, but I don't think it's a co-incidence that they are not "random" users, but only "new" users.

Obviously since they can log in to windows desktops, winbind behaviour must be different to Windows... but surely there has to be an AD component to this too.

The common-auth line you have below is precisely what I have.
