[AccessD] Read an ldb File

Dear List:
 
I'm about to re-invent the wheel by making an app that will read an ldb
file.  (Have a client that I can't update the back end because someone's
logged in and he can't find out who.)
 
Started by cribbing a module of a MS support site.  But them it occurred to
me that there might already be something on a site somewhere to do this.  
 
Does anyone know of such a program I could download?
