We have been investigating the use of X.500 in the Network, Systems and Applications management frameworks for the last couple of years. For those who are not aware yet, I would like to refer to our paper that was presented at the 3rd International Symposium on Integrated Network Management, San Fransisco, CA, April 1993, pp. 149-160, which discusses our experience of using the X.500 Directory Service in the network management framework. I can make the paper available on our ftp server if people are interested. Let me know please. Cheers! James W.
