Just FYI, I just finished conducting a training workshop on the LDM using Red Hat 9 systems for the workshop computers. The security configuration on every system was the "high" level default. The workshop went well -- in particular we did not need to execute the LDM as root. Having the LDM daemon program-file, rpc.ldmd, be owned by root and setuid-owner was sufficient. There were no independent firewalls between the workshop computers. Regards, Steve Emmerson LDM Developer
