this value if there is a port conflict. For information, see

You must specify the eDirectory port when you install clusters. Port 636 is the default port number
for eDirectory communications in the tree.

cluster and iManager. Port 5989 is the default setting for secure HTTP (HTTPS) communications
with OpenWBEM.
