Users simply identify themselves and the boot process continues.
What is not immediately apparent in the above model is how these multiple authentications take place in the NDS environment of NetWare 4.11. Due to the necessity of having the machine ID as the primary authentication on boot, we found that the machine's authentication would necessarily be a directory services connection. Since there can be only one Directory services connection per tree, all subsequent, or personal, authentications are in bindery mode. Being able to employ personal user IDs for primary connections would relieve this complexity entirely. Users logged in under their own accounts, on an NDS connection, would behave similarly to a nonremote boot client.
