[LDM #OKM-429702]: Setting up an LDM distributor


It is possible to build a non-standard LDM that doesn't use port 388 (via the 
"--use-port=<n>" option of the configure(1) script). It is not recommended, 
however, because 1) the so-built LDM will not be able to request data from any 
standard LDM-s without modifications to its REQUEST entries; 2) other, standard 
LDM-s will not be able to request data from the non-standard LDM without 
modifications to their REQUEST entries; and 3) to the best of our knowledge, 
the LDM has never been hacked in order to gain access to the host system 
(indeed, I would argue that that is impossible).

We've also noticed that sites that worry about port 388 usually have port 80 
wide open (for HTTP traffic), which is a greater security risk by many orders 
of magnitude.
