Oh, you've heard quite a bit from us :) (Adam and I are co-workers).  Aside 
from the patches I said I'd write (e.g. for 
accounts_max_concurrent_login_sessions also checking 
/etc/security/limits.d/*), which I really will have time to do one of these 

- The "world_writeable_files" check is flagging a ton of stuff in /proc

- The "no_shelllogin_for_systemaccounts" check doesn't allow /bin/false as one 
of the options.  This seems to be the default for most system accounts on our 
RHEL6 systems; I don't think that's something we're setting, but I could be 

dbus:x:81:81:System message bus:/:/bin/false
usbmuxd:x:113:113:usbmuxd user:/:/bin/false

It also seems to be flagging people with UIDs well over 1000, but GIDs of 100; 
do accounts like these fall into the category of "system accounts"?  I'm not 
sure where the logic for this is located.

Another oddity with this check is that --oval-results only ever gives me one 
entry, when it clearly would flag a bunch of stuff as failures.

Note that the above are using the version of OpenSCAP shipped with RHEL6.

That's mostly it; I do have one other thing (for which, amazingly, I have 
actually written a patch), but that's not exactly a false positive, so I'd 
rather start a new topic for it.
