Dell NetWorker 19.9 Administration Guide

Impact on network connections

When you enable individual user authentication, the NMC Server software might require more network connections. Additional network connections might firewall port requirements. The NetWorker Security Configuration Guide provides information about firewalls.

When you set the User Authentication for NetWorker system option, the NetWorker Authentication Service software creates a separate network connection the NetWorker Authentication Service to a NetWorker Server for each Console user that has an Administration window open to that server.

When you do not set the user authentication for NetWorker system option, there is only one network connection from the NetWorker Authentication Service to the managed NetWorker Server.
