object.UserName [= username ]
The UserName property is used to specify the name of the
user to retrieve information about. The username is a string which
may be in one of the following formats:
||Return information about user on the remote
||Return a list of users that are logged in on the system
specified by domain. Note that many servers do not honor
this request for security reasons.
||Return information about user on the system specified
Note that there is no standard format for the data returned by a
finger server. Some servers may return information such as the last
time the user logged in, if the user has any unread mail, and current
projects being worked on. The type of information is determined by
the type of server and the level of security, with many secure
servers not providing any service to systems outside of it's own
