Comment 1 Nate Straz 2015-08-13 20:17:13 UTC 
Description of problem:

I'm getting different output from `pcs status pcsd` whether I run it from an ssh session or the serial console.

Serial console:
[root@west-01 ~]# id -a
uid=0(root) gid=0(root) groups=0(root) context=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023
[root@west-01 ~]# ls -l /proc/self/fd/0
lrwx------. 1 root root 64 Aug 13 16:14 /proc/self/fd/0 -> /dev/ttyS0
[root@west-01 ~]# pcs status pcsd west-02
  west-02: Unable to authenticate

SSH:
[root@west-01 ~]# id -a
uid=0(root) gid=0(root) groups=0(root) context=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023
[root@west-01 ~]# ls -l /proc/self/fd/0
lrwx------. 1 root root 64 Aug 13 16:15 /proc/self/fd/0 -> /dev/pts/0
[root@west-01 ~]# pcs status pcsd west-02
  west-02: Online
