Create an alias using a subdomain of other user's domain

Hi! On my server, I need to create an alias on an account using a subdomain of another user's domain. I'll try to explain like this: * I have 4 accounts on the server: user0.com (user = user0) user1.com (user = user1) system.user1.com (user = system) dev.user1.com (user = dev) * user1.com has user2.com as an alias * I need to create two aliases of system.user1.com: system.user2.com system.user3.com Currently, when I try to add "system.user2.com" as an alias on dev's cPanel account, the error I'm getting is: There was an error when the system attempted to create the alias. Park::park failed: (XID rp6qdn) The domain "system.user2.com" may not be created by "dev" because "user2.com" is already owned by another user. Seeing that I can use several subdomains of a unique domain as separate domains when creating accounts (user1.com, system.user1.com and dev.user1.com), I imagine that there may be a way to get the same "freedom" when handling aliases. Of course, I know that allowing this is a security flaw in shared environments but I'm the only one that has accounts on this server so nothing happens that I don't want to. Without cPanel, this would be easily handled by manually editing httpd.conf and corresponding vhosts, but that is not the proper way on cPanel... I hope someone is able to help me figuring this out! Thanks ;)

  So... It turn out that this was, in fact, quite easy to do but I really wasn't able to find a solution when googling, so I leave it here for future reference. To do what I needed, you only need to turn on a specific option from Tweak Settings (Home > Server Configuration > Tweak Settings): Allow cPanel users to create subdomains across accounts That's it! Thank you cPanel support for pointing this out!

  QUESTION: @cPanelLauren @cPanelRex If I have used this system to set up a cross account subdomain as outlined above by Santiago Botto , then what happens if I update the tweak settings to refuse this ability; do the existing cross account relationships remain? Ie. I want to turn it on, do what needs to be done and then turn the setting off so it doesn't stay on by default.

  > Allow cPanel users to create subdomains across accounts The important word there is "create", once it's created it will stay and work even if that setting is OFF.
