What is the default of `-b`?

Hi,

The man page says the following.

`-b` *searchbase* : Use *searchbase* as the starting point for the search instead of the default.

I'm wondering what is the default. If I don't specify -b, I will get an error. Does anyone know how show all the contents from the database? Thanks.
