Remove readycloud users

I think I figured out how to remove the ReadyCloud users from a Neatgear ReadyNAS on version 6.10.10.

I was upgrading from an old ReadyNAS 314 (2TBx4) to an newer-old ReadyNAS Pro 6 (3TBx6)
I did a configuration backup from the RN314 and restored to the Pro6, then backed up the configuration on the Pro 6, and inspected the differences.

Both NAS systems are on firmware v6.10.10. I expect that the commands should be functional in 6.10.x. Importing the configuration to the Pro 6 did not import the ReadyCloud users or permissions. That helped with the comparison. After migrating all of my data to the Pro 6, I then started poking around the RN314 to see if I could figure out how to remove the ReadyCloud users from the system.

I do believe that this is a superficial cleanup that doesn't really NEED to be done, but, if you're like me, you just want it to be clean and simple. Here is how I did that.

Disclaimer: Make sure you have a good backup of your configuration and your data before doing this process. [System] > Settings > Configuration Backup >Download - Everything > [Download Configuration Archive].
While I am confident that these commands should work, you assume the full responsibility for any errors or issues that may occur. Use at your own risk.

*

First, confirm that none of your internal users have an email address as their username. [Accounts] > Users > NAME should not contain any '@' signs.
If you are using email addresses AS usernames, then you may have to manually run the commands,adjusting them to search only for the list of ReadyCloud users you want to delete.

Steps with descriptions. (batch of commands listed at the bottom)

1. Enable SSH on ReadyNAS [System] > Settings > SSH > Checkmark Enable SSH & Enable password authentication > [Apply]
   1. Use Putty/etc. to SSH into the Name or IP of the ReadyNAS
   2. Logon as user : root
      • Password should be the same as the admin account. (Or login as admin, then 'su' into root, with the same password.)
2. This command will remove the ReadyCloud users from being listed in the [Shares] section and in the Folder Permissions.
   • mv /opt/readycloud/etc/registration.conf /opt/readycloud/etc/registration_tmp.conf
3. Remove the Invalid user line from the shares. Note: May not be necessary, but it does clean it up.
   • sed -i.bak '/^[[:space:]]*invalid user/d' /etc/frontview/samba/Shares.conf
4. Set every ReadyCloud user to #-comment.
   • sed -i.bak '/^#/!s/^/#/' /etc/frontview/samba/usermap.conf
   • - OR - Remove any line that contains an '@' since it is a ReadyCloud Username
   • sed -i.bak '/[@]/d' /etc/frontview/samba/usermap.conf
5. Remove the Invalid user line from the samba share configs. Note: May not be necessary, but it does clean it up.
   • find /data/._share -type f -name samba.conf -exec sed -i.bak '/^[[:space:]]*invalid users/d' {} +
6. Removes the ReadyCloud users with the user name as an email address.
   • sed -i.bak '/@/d' /etc/samba/smbpasswd
7. Removes ReadyCloud users from the passwd file. - Remove all lines with email @ before the first :
   • sed -i.bak '/^[^:]*@[^:]*:/d' /etc/passwd
8. Removes ReadyCloud users from the shadow file. - Remove all lines with email @ before the first :
   • sed -i.bak '/^[^:]*@[^:]*:/d' /etc/shadow
9. Finally Reboot the ReadyNAS, from SSH or from the Admin page.
   • ssh command: reboot

After the steps are complete, and you confirm everything works, make sure to turn SSH back off in the Admin settings.

If the ReadyCloud user was an owner of a file or folder, then you may need to take ownership of those files manually in file explorer, or by resetting the permissions in the share settings.

Note: For each file, you can run 'cat [filename]' to see what it contains, then run the sed command without the '-i.bak' to see what it will do.
Example:

• cat /etc/passwd
• sed '/^[^:]*@[^:]*:/d' /etc/passwd

Make sure that the only users missing from the 'sed' list are the ReadyCloud users.

sed -i.bak2 '/[@]/d' /etc/frontview/samba/usermap.conf
find /data/._share -type f -name samba.conf -exec sed -i.bak '/^[[:space:]]*invalid users/d' {} +

I hope someone finds this helpful.
I still love Netgear ReadyNAS, and I'm going to use it till the wheels fall off.
