Re: I just updated to bind-9.7.2b1and suddenly my DLZ is no longer working! It segfaults with the following error:

Some versions of DLZ used '%' to demarcate tokens, but they can cause problems 
for the LDAP driver.  Subsequent patches have changed the token demarcation to 
'$'.  It looks like your updated version (that's failing) is using the '$' 
symbols.  If your config file is a few years old and still using the '%', it 
will suddenly fail at startup.

Simple solution is to check what your file is using around the tokens, and if 
it's '%', change them to '$' after the upgrade.
