QE will need steps to verify this

This BZ is a suggestion for a general solution of the related issues. It's out of scope of RHEL 7.2, moving to RHEL 7.3.

Upstream ticket was fixed:

Petr,

Can you provide steps to reproduce this?

Thanks,
Scott

1. have a user "fbar" which doesn't have rights to read everything (i.e. non-admin).
2. have object "foo" (let's assume other user)
3. "foo" has attribute(s) for which fbar doesn't have read rights, e.g., telephonenumber (for this example)
4. "foo" has a different attribute(s) which user can read, e.g. cn
5. have ldapsearch  with filter (|(cn=foo)(telephonenumber=foo)) I.e. (|(true)(false) -> should return object
6. with fix it will return fbar, without fix it won't

Epected is that it will because user can read the one for which it is evaluated as true.

Basically this is a dup of bug 1316328 and related DS ticket https://fedorahosted.org/389/ticket/48275 both contains additional info.

Verified.
