@zMan: SAF, itself, has exits that could be used to make security decisions and 
even overrule those made by the ESM.

@coasthermit: You experienced what it known as Failsoft processing. RACF itself 
wasn't disabled but its databases were, so it turns to the operator for 
approval of every access authorization check. I've only come across one 
installation that had an exit to do just what you suggest.

Many years back I IPLed my onepak system with RACF disabled to see what 
happened.Every access of a resource sent a reply prompt to the console for 
YES/NO.It took a while but I eventually got enough of MVS up that I could logon 
to TSO/E.I considered writing my own RACF exit that returned OK for every 
access request, but in the end I just built a default RACF data base for that 
system to use.Maybe SAF still works the same way.

On https://www.ibm.com/docs/en/zos-basic-skills?topic=zos-what-is-saf , IBM
says:

> System authorization facility or SAF is an interface defined by MVS™ that

Someone on r/mainframe asks what SAF does without an ESM. I'm thinking "not
much", but the last sentence above sort of suggests otherwise--unless "SAF
either processes security authorization requests directly" means "returns
RC=0 in all cases", in which case it would be accurate but IMHO overly
vague. Thoughts?
