back-sql mysql and multiple DITs

Hi, I have tried to set up a single instance of slapd serving information from two DITs that have been defined in separate mysql databases. I can comment out the database entries for either DIT, and everything works for the other DIT. But it won't support the two DITs simultaneously (it seems random which DIT will return results and which returns "no such object" when I restart slapd with both DITs configured). All the odbc stuff for both backends seems fine, isql runs and of course either database can be accessed through ldapsearch if it is the only one slapd serves. I can even run two instances of slapd, one with each DIT and successfully query them separately with ldapsearch, but I'd prefer one instance with the two DITs if possible. Could you please help me get this running, or is it just the law that only one sql backend can be used per server ? Many thanks Alan Slaptest says (when both DITs are defined in one slapd.conf)...
