Hi Rowland
I may have some good news: with recent versions of pam_krb5 and cifs it 
shouldn't be necessary to do anything. You just get the cache when you 
go to the share. If you can get that far of course. The reason for our 
failure was:
<feel thick>
common-auth has: auth [success=2 default=ignore] pam_krb5.so 
Our test user was 20000
</feel thick>

So, users in the normal 3000000+ AD range get there fine:)
