Try this in various contexts. 1. Go to Settings -> Users -> Permissions -> Check permission (that is the location on a course page, it is slightly different in system / categories / modules). 2. Select a user (you should probably try this for various different users). 3. Verify that, at the top of the summary of the user's permissions, it shows all the user's roles in this context or parent contexts, including 'authenticated user', 'front page role', etc. 4. Role should be shown with a link to view the role definition of that role (if you have permissions to do that) and with a link that takes you to the context in question.
