No problem. Glad it helped…
I can’t recall but I believe before these steps, to even allow other users to ssh in WDMyCloud, we first need to modify the file ‘/etc/ssh/sshd_config’ to comment out ‘AllowUsers root’ then restart sshd.
Related to your step 1 & 2, I’ve posted few fixes not long ago about some bugs in firmware v3 which WD didn’t even fix in v4! In the fix, I included an optional patch to easily create user with its home path via WD’s webUI.
