I've built a Canvas App using Signed Requests and therefore I need the Permitted Users option set to "Admin approved" (otherwise Salesforce doesn't send any Signed Request). I've set this option to "Admin approved" in my App and everything works fine when I use the Canvas App Previewer.
However, when I package the App and install it in another developer environment, the option Permitted Users is set to "All Users" :( Therefore I have to change the value of this option to be able to receive the Signed Request.
Is there any way to make things simpler for the admin that will install my App such as setting the default value of the Permitted Users value to "Admin approved" ?
Thanks in advance for all your answers!
