Description Florian Weimer 2018-05-23 16:28:09 UTC

+++ This bug was initially created as a clone of Bug #1392540 +++

Description of problem:
Newly provisioned RHEL 7.3 systems in IPA environment do not have functioning autofs due to the 'sss' option not being added to the automount entry of nsswitch.conf.

Version-Release number of selected component (if applicable):
ipa-client-4.4.0-12.el7.x86_64

How reproducible:
always

Steps to Reproduce:
1. ipa-client-automount

Actual results:
automount:  files 

Expected results:
automount:  files sss

Additional info:

Comment 1 Florian Weimer 2018-05-25 09:37:18 UTC

We should drop all references to nis, nispuls, and add sss as requested.

Comment 2 Florian Weimer 2018-05-25 10:00:21 UTC

Should we list sss before files to obtain better caching?

Here is what I came up with so far:

passwd:     sss files
shadow:     files sss
group:      sss files

hosts:      files dns myhostname

bootparams: files

ethers:     files
netmasks:   files
networks:   files
protocols:  files
rpc:        files
services:   files sss

netgroup:   sss

publickey:  files

automount:  files sss
aliases:    files

Comment 3 DJ Delorie 2018-05-25 17:06:15 UTC

No, because that precludes the use of local files to provide local overrides, such as a machine-specific root password

Comment 4 Simo Sorce 2018-05-25 17:36:23 UTC

sssd never provides a root account by design.
as a default it makes sense, overrides are special actions that can be dealt with by manually changing nsswitch.conf if you have a conflict (but note that sssd also has a way to remap cerntal users so you can avoid conflicts should you need to).
