We would need to invent one, like ipaVirtualOperation with one MUST attribute
"cn" and then apply it to all virtual operations and replace nsContainer. It
should not be a problem though as we do not provide API to handle the virtual
operations. There are very static.
Simo, Rob, would you be OK with changing virtual operation objectclass to our
own one to have a better control over it?

Hm, exclusion of this one is probably not needed. User would really only see
the containers for Definitions and Templates, not the real configuration

Makes sense. Right now, we have 2 types of objects here:
1) system users: simpleSecurityObject objectclass
2) system groups: groupofnames objectclass
We can make 2 ACIs, allowing those:
- allow reading "uid, objectclass" of "simplesecurityobject" to authenticated
- allow reading "cn, member, objectclass" of "groupofnames" to authenticated
