A client session started with the -virtualnodename option prompts for a
user name and password. It is possible to supply a TSM administrator
name and its associated password rather than a node name and its password.
I have done this with an administrator account defined as a client owner
for the node involved, but with no other special privileges. I have
also done this with an account having SYSTEM authority. I don't know
whether any of the lesser varieties of server-wide authority would
suffice.
