| Description | The human readable name of a human user using the client
machine. If more than one user name are available
simultaneously, it is an implementation-dependent matter as to
which is used here. However, if the user name changes, this
object should change to reflect that change.
Non-human user names like 'root' or 'administrator' aren't
intended as values for this object. If the client has no
recorded user name or the agent is unable to learn a user
name, this object will be a zero-length string. |
