I have tried installing libpam-krb5, and it adds the following line to common-,auth,passwd,account and session:-

auth	[success=3 default=ignore]	pam_krb5.so minimum_uid=1000

However, with that configuration, no users can log in (could this be because the AD server had no RFC2307 unix extensions)... so I have removed the package, and now I'm back to the situation where only the 3 most recent users cannot log in.

Note that the users who can't log in, can authenticate with kinit!
