Description Jakub Hrozek 2016-01-15 10:06:51 EST
Description of problem:
Upstream libc recently gained the possibility to merge group members from different Name Service modules. We should backport this feature to RHEL.

This would mainly enable deployments that depend on centralized directories to define members of well-known local groups (like wheel) in the centralized directory in addition to local files

Version-Release number of selected component (if applicable):
Whatever will be in RHEL-7.3

How reproducible:
always

Steps to Reproduce
1. set "group: files [SUCCESS=merge] sss" in nsswitch.con
2. define a group wheel in IPA or AD
3. getgrnam(wheel)

Actual results:
only local members are returned

Expected results:
getgrnam returns both members of the local wheel group as well as the members defined in the remote directory are returned
