Hello,
This adds managed read permissions to the compat tree.
For users it grants anonymous access; authenticated users can read
groups, hosts and netgroups.
I'm unsure if this is what we want to do for groups, but "Read Group
Membership" is only granted to authenticated users by default, and the
compat tree exposes memberuid.

Self-NACK, there's a typo (though I could swear I tested this :/)
Fixed patch attached.
I tested and it looks and works OK, ACK from me. We can wait till tomorrow to
see if there are no reservations from Alexander or Rob.
I think we need a bit more fixes. Here is ACL log for an anonymous

createTimestamp is operational attribute and is synthesized by
slapi-nis, there is no problem allowing access to it. I think we can
allow following operational attributes:
createTimestamp, modifyTimestamp, entryUSN, creatorsName, modifiersName,
entryDN, hasSubordinates, numSubordinates
Ah, ok, probably yes. At least for some of them - CCing Simo. For example
entryUSN is used by SSSD - CCing jhrozek to confirm. So it should be allowed
for whole FreeIPA DIT. So this change is not so related to these patches.
Do we also want to expose attributes like creatorsName/modifiersName? Do we
consider that a public information or juts audit-like information for DM only?
Finally, ipaNTSecurityIdentifier may be allowed to access too, I didn't
run ipa-adtrust-install on this machine yet.
I do not think that this attribute is written to cn=compat (did not see it in
config) - is it?
The same set should be allowed for primary tree.
IMO this should be just one global permission/ACI, set for DIT root.
I experimented a bit, by setting SSSD with a simple LDAP provider
talking to a compat tree (with views enabled, but that doesn't change
anything) and I think we need to move to ipabindpermruletype=anonymous
or otherwise such setup will not work at all. Attached is my take at it
on top of Petr's patchset.
You can ignore views-related ACIs for time being.
