Set your dynamic linker to debugging mode(s), and see if you can get a

Matter is, OpenLDAP loads SLAPI plugins (as well as backend modules)
with the help of libtools' ltdl library, a cross-platform wrapper over
platform specific dynamic library loading mechanisms. If you know how to
enable debug mode for ltdl, I'll be thankful if you tell me about it :)
Perhaps you could compile libltdl defining LT_DEBUG_LOADERS.
However, this is probably beside the point. I'd sooner check with a
debugger if you're actually calling dlopen("/proper/path/to/the.so"). If
you are, it's unlikely that you'll need to debug libtool itself; it has
successfully performed its wrapping and things are now in the hands of
your linker. I doubt you'd find anything of note by debugging libtool
itself in this scenario.
If you never make it to an actual dlopen(), you're right, you may want
libtool debugging.
