Technical issues notwithstanding, I would suggest that the behavior was driven (at least in part) by audit demands that multiple logons with a single ID be blocked to prevent users from sharing ID's.
Giving one user multiple ID's is also perceived to be a sharing ID risk. I guess the audit approved path would be to require the user to sign on, perform the task, then sign off. Indeed, our last audit looked at inactivity time outs. -----Original Message----- From: IBM Mainframe Discussion List [mailto:ibm-m...@bama.ua.edu] On Behalf Of Don Williams Sent: Friday, April 23, 2010 10:15 AM To: IBM-MAIN@bama.ua.edu Subject: Re: Multiple logon SMCS possibility Several years ago, I asked IBM why they prohibit users from concurrent sign-on to multiple consoles, and was told that it is working as designed. He noted that I was not the first to complain. I hope that IBM will change their design and allow users to sign-on to multiple consoles. Until then, you'll have give users multiple ids to circumvent that restriction. In many shops that means you'll have to get a security policy waiver before assigning multiple ids to the same person.
