[LDM #KGJ-740033]: Problems with LDM

Peter,

If you're having to run the portmapper daemon in order for the LDM system to 
work, then I suspect that the LDM server isn't getting its well-known port, 
388. This could be because the LDM server program, bin/ldmd, isn't owned by 
"root" and setuid.

What is the output of the command

    ls -l bin/ldmd bin/hupsyslog

executed by the LDM user in their home-directory?
