I tried to replicate this using 2 real F23 systems.

I copied my id_rsa.pub on my local system to /root/.ssh/authorized_keys on the remote
machine. 

 [egreshko at meimei ~]$ whoami
egreshko
[egreshko at meimei ~]$ ssh root at acer
Last login: Sat Jan 23 07:37:23 2016 from 192.168.1.18
[root at acer ~]# whoami
root
[root at acer ~]#

Is this what's failing for you?
