It is a standard setup with the standard read-only public community.
I can snmpwalk the normal mibs fine. For example, I can smnpwalk the
"standard" mib names such as system, tcp, hwStorage, etc.
Only when I try to access the OMSA mibs do I get nothing back (no error,
That doesn't mean it isn't access, but it does mean at least some access
is being granted.

I did try adding:
view all included .1
access notConfigGroup "" any noauth exact all none none
and it didn't change anything in a noticible way (things that used to
work still worked, things that used to not work still didn't work).

I basically tried that (as above, just adding the view all and access
lines, and also to the fuller extent of changing from public to another
name and all that, and it made no difference.

Yes, I realized that about 5 seconds after sending the message. And I
thought about posting an immediate follow up to make it clear I could
read everything except the OMSA values, but decided to just wait and
see what happened with the original message.
