Assign Roles
When you assign a role to a user, you are granting them permissions for the current context and all "lower" contexts.
Contexts:
- System (the entire installation)
- Front Page (the landing page)
- Course Categories
- Course Sub-categories
- Courses
- Blocks and Activities
For example, if you grant a Student role to a user in a Course, they will have that role for the course, but also all Blocks and Activities inside that course. Their actual permissions may depend on other roles and overrides that have been defined.
