Question Restricting/sandboxing Child site administration/access

[RobCSB]

I am a new Plesk ONYX customer.

I have a subsciption configured and functional...let's call it SAMPLE.COM. It's up and running no problems.

I have created a child domain, CHILD.SAMPLE.COM. That site is up and running.

I just noticed that the user account specified for FTP/SSH access for SAMPLE.COM can manage CHILD.SAMPLE.COM.

How can I create a limitation so that I can have a different user who can only manage CHILD.SAMPLE.COM. (By Manage, I really mean FTP/SSH access and limited access to that site via the PLESK Console.

I do not want to have a situation where child sites administrative access accounts can have access to all other child sites. They need to be sandboxed so that CHILDUser can only manage CHILD.SAMPLE.COM, not the parent (SAMPLE.COM nor CHILD2.SAMPLE.COM, etc.)

Thank you.
