Re: LTI configs when add external tool is switched off

Hi Jon,

Yes, it is. the 'mod/lti:addcoursetool' capability controls, as you can probably guess, the ability to add/create a course tool. Since 4.3+ no longer support setting up a tool at the instance level (i.e. all tools must be created prior to use), removing this capability for the relevant roles would prevent those users from creating tool in their courses, effectively locking that down.

They'd still be able to use any tools which are available to that course with the caveat that the tool must be available in the activity chooser for that course. The ability to show the tool in the activity chooser (i.e. permitting its use as an activity) exists in both the site level tool configuration and in the course tool table. At the site level, that's just set by admin, as you'd expect. At the course level, only users with the "mod/lti:addcoursetool" capability can toggle this. In this way, the toggle is treated the same as adding/editing a course tool configuration. Once you lock down course tools for teachers, they won't be able to enable course tools for use in their course, so you need to make sure the tools are available to them.
Either:

a) Set the "Tool configuration usage" to "Show in activity chooser and as a preconfigured tool" at site admin, at which point the tool will be available in the activity chooser of all courses, or;
b) Toggle the "Show in activity chooser" at the course level, of course using a role that has the "mod/lti:addcoursetool" capability.

Once the tool is in the activity chooser, you can just use it like normal.

Hope that helps

Any feedback most welcome
