If the Samba folks are dumping the entire database and caching it, it just seems to me to be another instance of their lack of comprehension about how to use LDAP.
Honestly, the smbd may only do that once, I don't really know. I'm not familiar with the internals, so a judgement on the Samba folks may be premature.
