The following settings may be changed by an administrator in Settings > Site administration > Users > Permissions > User policies.
Role for visitors
Users who are not logged in to the site will be treated as if they have the role specified here, granted to them at the site context. The role of Guest is the default and the recommended setting for standard Moodle sites. The user will still be required to login to participate in an activity.
Role for guest
This option specifies the role that will automatically be assigned to the guest user. This role is also temporarily assigned to non enrolled users when they enter a course that allows guests without password.
Default role for all users
The default role for all users should normally be set to Authenticated user. If it is set to Student then the result is that all students are enrolled on all courses.
Note: The default role for all users should never be set to Guest.
If not set, then visitors must click the "Login as a guest" button before entering a course which allows guest access.
Note: If auto-login guest is set, the guest login button also needs to be set to show (in Settings > Site administration > Plugins > Authentication > Manage authentication), even though visitors won't necessarily use it.
Hide user fields
The following user fields appear on users' profile pages. Certain user fields are also listed on the course participants page. You can increase student privacy by hiding selected user fields.
Description, city/town, country, web page, ICQ number, Skype ID, Yahoo ID, AIM ID, MSN ID, last access, My courses and first access and groups
- User fields on users' profile pages are hidden from all users with the capability moodle/user:viewhiddendetails not set.
- User fields on the course participants page are hidden from all users with the capability moodle/course:viewhiddenuserfields not set.
If enabled Moodle will check whether a user's email address has an associated avatar at Gravatar. If so, and the user has not uploaded an image, the Gravatar will be displayed.
Unsupported role assignments
Unsupported role assignments are role assignments in contexts that are not marked as suitable for that role, such as course creator in activity or course, or teacher in the user context.
An administrator can check for any unsupported role assignments across the site in Settings > Site administration > Users > Permissions > Unsupported role assignments.
