Hide Forgot
An issue was fixed when searching in IPA didn't return all valid results if user didn't have read rights for all attributes in the query even though it was an "OR" filter.
This bug is created as a clone of upstream ticket: https://fedorahosted.org/freeipa/ticket/5168 See tickets #5167, #5055, #5130 A general solution for this issue is needed. Even if we make default permissions in a way that normal users will be able to search all object, someone can create a permission to hide just one attr and the search will fail. Possible solution is to perform a search with very limited number of attrs or allow to define the search attrs.
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.

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.
