Ceph

I have been running ceph-docker project with ceph/daemon:centos-latest image based on 'hammer' release on RHEL 7.1 and Centos 7.1 hosts for some time now and it runs just fine.

Command line used: docker run -d --net=host -v /etc/ceph:/etc/ceph -v /var/lib/ceph:/var/lib/ceph -e MON_IP=10.10.191.104 -e CEPH_PUBLIC_NETWORK=10.10.191.0/24 ceph/daemon:centos-laters mon

When I upgraded by host OS [yes right, host OS] to RHEL 7.2, I am hitting numerous cephx issues while running same image and command line.

As I can infer from logs, mon has done the requisite setup and started to run. I have attached the complete log for debug.
Can someone please let us know as to why cephx errors are reported. Unfortunately the same runs fine on RHEL 7.1, Fedora Atomic hosts and not with RHEL 7.2 kernel.
