ATE reports the local PC user name and machine name to the server when the connection is established. This information can then be retrieved with the use of GETUSN.SBR.
In the case of ATSD (A-Shell Telnet Server under Windows), the user name from the local PC will be used to override the default service user name for the job. (This is much more useful than the generic system service user name that would otherwise be reported in SYSTAT, the ashlog.log, or any other place where the user login name is displayed.)
