SSH fails on FSO

[max]

I flashed FSO 5.1 (back after several months) and it works quite well.
However, when I attempt to SSH into my Freerunner, I get a "Permission
denied (publickey,password)" after I enter the password. Assuming that
root ssh is disabled, I tried creating a user on the device, and then
attempt SSH from the desktop. It still gives the same error.

Am I doing something wrong? Is there some sshd configuration I need to adjust?

Googling didn't help much.
