Great!  (and yes, I'll need to look into the segfault once I reproduce
your success).

We should just replace it with the samba mapping.  (Because we will
never bind using any other user, and normal users  - ie those in
dc=samba,dc=example,dc=com will not bind to the backend directly)

My original work to spit 00core.ldif from the 'important, but not quite
core' schema is showing it's age.  You will probably need to re-adjust
the balance, while trying not to import the whole schema (due to
conflicts with the AD schema).
