Description of problem: A recent Fedora 29 with testing repos enabled causes this new SELinux violation:

# journalctl -b | grep type=14
Nov 13 05:52:34 localhost.localdomain kernel: audit: type=1400 audit(1542106354.631:368): avc:  denied  { write } for  pid=1925 comm="sss_cache" name="config.ldb" dev="dm-0" ino=8744743 scontext=unconfined_u:unconfined_r:passwd_t:s0-s0:c0.c1023 tcontext=system_u:object_r:sssd_var_lib_t:s0 tclass=file permissive=0


Version-Release number of selected component (if applicable):
shadow-utils-4.6-4.fc29.x86_64 (provides chpasswd)
sssd-2.0.0-4.fc29.x86_64
selinux-policy-3.14.2-42.fc29.noarch
kernel-4.18.17-300.fc29.x86_64


How reproducible: Always


Steps to Reproduce:
1. Create current Fedora 29 with testing repositories enabled and SELinux installed
2. Create a test user
3. Try to change password of test user with chpasswd

Actual results:

[root@localhost ~]# journalctl -b | grep type=14

[root@localhost ~]# chpasswd
test:foobar
