/*++**************************************************************
  NAME:      ConnectAndBindToDefaultDsa

  does just what the function name says.  We call the default
  DSA and bind to it.  We then return the ldap handle

  MODIFIES:  ppLdap -- PLDAP returned that describes the connection
                       (now bound) to the DSA as requested
  TAKES:     BindTarget -- target (domain name or DC name) passed to ldap_open

  RETURNS:   TRUE when the function succeeds.
             FALSE otherwise.
  LASTERROR: not set.

  LOGGING:   printf is called on failure

  CALLED BY: anyone
  FREE WITH: ldap_unbind
