RE: disable all Q* ibm supplied profiles and chaning default passwords

Why do I remember having problems whenever QUSER would get disabled. It's been a long long time ago, .. perhaps it was a SNA issue?
And why would EIM/SSO allow password *none profiles to sign on?

Hi, Jim,

One interesting wrinkle ... you can sign-on to a user profile that has a password set to *NONE, if you are on a system that is using EIM/SSO.

Only if you *DISABLE the profile, can you totally prevent it from being used to sign-on interactively.

This does not prevent those profile(s) from being used to run batch jobs or "services."

Just saying ...

I think this thread has pointed out some of the misconceptions that surround ibm i security.
One point that I've not seen yet - there is a difference between a. disabling a profile or b. changing a default password to *NONE (to never be used to sign on) Carol Woodbury's books recommended QPGMR, QSRV, QSRVBAS, QSYSOPR, QUSER all to set to *NONE The profile can be used by parts of the OS, but not to log in.
New releases come this way, but if you are carrying 30 years of baggage, restoring to new hardware, it takes some cleanup.
