Capabilities/moodle/role:assign

• This allows a user to assign roles in a given context (system, front page, course category or course).
• Note that to assign a role A to another user, the user doing the assignment has to hold a role B so that role B is permitted to assign role A. This is controlled in 'Allow role assignments' in Settings > Site administration > Users > Permissions > Define roles. This is logical because even though a teacher might have moodle/role:assign, in most situations we only want them to be able to assign users the student role, and not the manager role in their course.
• This capability is allowed for the default roles of manager and teacher.
