Looks like I had some bad data in the db. I dropped and reloaded my  
tables with data from the dlz sample data scripts, grabbed one of the  
domains, changed the names and loaded this data into the db.

dlz is now working. Great!

BUT, I'm a little concerned, shouldn't I expect something different  
the a fatal error if dlz returns bad data?

Oh, and Todd, thanks for the bind-sdb help. Having only compiled from  
sources and not being familiar with rhel I didn't understand which  
rpm's were required and I basically was getting no output errors, just  
silence which I thought was strange.

I have another question relating to bind-chroot. I am not using this  
yet but now that I have established the basic functionality is it  
generally excepted that bind9 should be chrooted?

If I use bind-chroot rpm are most people communicating with mysql via  
tcp port?

Are there any docs on making the mysql socket available to chrooted  
bind?

Sorry to lean so heavily on this list but I have really struggled to  
find documentation on dlz.
