Howard,
  The fact that the openldap administrator is required to run db_recover
manually after a crash of the BDB backend is NOT documented in the
openldap manual pages nor the "OpenLDAP 2.1 Administrator's Guide".  In 
fact, "db_recover" is NEVER even used in the man pages or the 
Administrator's Guide.

  Thank you, I now have a clearer understanding of why I think the BDB
Backend is, in my personal opinion, not ready for real use.
  
  Constructive comments on why such a critical fact would be entirely
missing from the openldap documentation are welcomed.  Flames and
insults will be silently ignored.
