Please attach AVCs that you see when reproducing this scenario.
Comment 3 Roshni 2016-02-05 10:18:26 EST
I have not yet reproduced this issue on RHEL 7 but once https://bugzilla.redhat.com/show_bug.cgi?id=1303214 is fixed we will be running into this issue. The same happened on RHEL 6.8, the AVC's on RHEl 6.8 can be found here https://bugzilla.redhat.com/show_bug.cgi?id=1299066#c7
Comment 4 Milos Malik 2016-02-05 11:00:00 EST
Some of the AVCs listed in BZ#1299066 contain "success=no", which means they appeared in enforcing mode. The selinux-policy developers need to see all AVCs triggered by the scenario to fix it properly in policy. Could you switch the sssd_t type to permissive and repeat your scenario?

# setenforce 1
# semanage permissive -a sssd_t
(repeat your scenario)
# semanage permissive -d sssd_t

This is rhel7 bug and AVC si fixed in:
[root@hp-dl380pgen8-02-vm-5 ~]# rpm -q selinux-policy 

Can we close this for RHEL7?
