How are they members of this group?  

The thing that Samba's classicupgrade code does that the operational
Samba 3.x DC didn't do by default is set 'ldapsam:trusted = yes'.  This
means that if you were using groupOfNames based groups, we might not
read that correctly in our internal handler, but nss_ldap would have, if
configured.

It's just a guess, but somewhere to start.  Otherwise, perhaps look at
this group and see if there is anything different about it?  Can you
show me the LDIF?
