You may be right. Even after reading openldap's back-sql backend it is 
hard to imagine exactly what is happening.

I didn't know there was something out there to turn on logging. How do I 
get logging? Do I use an API command to turn it on, recompile freetds 
with an option, recompile unixodbc with a debug option, or something 
like that?

I haven't heard of this problem.

In the meantime I've changed openldap to insert "convert(integer,?)" 
wherever it tries to bind an integer parameter. But now I have to use a 
grossly hacked openldap server to get it all to work.
