Description of problem: * oddjobd cannot communicate with SSSD when /etc/nsswitch.conf mentions "sss" before "files" Version-Release number of selected component (if applicable): oddjob-0.30-5.el6.x86_64 oddjob-mkhomedir-0.30-5.el6.x86_64 selinux-policy-3.7.19-279.el6_7.7.noarch selinux-policy-doc-3.7.19-279.el6_7.7.noarch selinux-policy-minimum-3.7.19-279.el6_7.7.noarch selinux-policy-mls-3.7.19-279.el6_7.7.noarch selinux-policy-targeted-3.7.19-279.el6_7.7.noarch How reproducible: always Steps to Reproduce: 1. get a RHEL-6.7 machine 2. install, configure and start sssd 3. modify /etc/nsswitch.conf # grep sss /etc/nsswitch.conf passwd: sss files shadow: sss files group: sss files services: sss files netgroup: sss files # 4. call oddjob-mkhomedir via D-bus # gdbus introspect --system --object-path / --dest com.redhat.oddjob_mkhomedir 5. search for SELinux denials Actual results (enforcing mode): ---- type=PATH msg=audit(10/27/2015 16:30:45.157:1381) :
