We do log it, but at level 10 which is just horribly noisy,
particularly for things that touch ldb.

Perhaps try: 

 log level = 10 ldb:0

Look for 

 basedn: ....
 filter: ....

or SearchRequst: filter: [....]

This code is so-unloved it appears to print the search twice, but this
might give you a place to start.

Sorry for the delay in the response.
