OA47960: CL/SUPERSESSION SAMPLE KLSONTSO MAY REVEAL CREDENTIALS IN ENVIRO NMENTS WITH HIGH NETWORK LATENCY

APAR status

• Closed as program error.

Error description

• You are running CL/SuperSession with the initial dialog
  sample KLSONTSO to automate user's logon to TSO.  The
  environment has unusually long network lag.  Occassionally,
  when a user attempts to logon, the logon dialog types a user
  ID and password as soon as the keyboard unlocks, although
  the TSO LOGON menu is not displayed.  This can result in the
  clear text password appearing on the user's screen.
