Since the "olcBdbConfig" is defined in back_bdb module, and back_bdb registers it when loaded, I find it hard to figure out how an error message related to "olcBdbConfig" being undefined could mention the module that would load it. As a general rule, trying to use a module prior to loading it sounds a bit braindead. It is just one step away from documenting the need to switch the computer on before using ldapadd. p.
