      1. Enable auto-login guest (Site administration > Users > Permissions > User policies - Auto-login guests).
      2. Now visit each of these admin pages. You should be prompted to login and not get an access issue:
        • admin/search.php
        • admin/plugins.php
        • admin/qbehaviours.php
        • admin/qtypes.php
        • admin/roles/manage.php
        • admin/roles/usersroles.php?userid=2&courseid=2 (This will redirect you to enrol in the course and not to login) You will also be logged in as a guest and will need to log in as a user and then log out to get back to the original logged out state)
        • admin/tasklogs.php
        • admin/timezone.php
        • admin/tool/monitor/managerules.php
        • admin/tool/oauth2/issuers.php
        • admin/tool/task/scheduledtasks.php
      Show
      Enable auto-login guest (Site administration > Users > Permissions > User policies - Auto-login guests). Now visit each of these admin pages. You should be prompted to login and not get an access issue: admin/search.php admin/plugins.php admin/qbehaviours.php admin/qtypes.php admin/roles/manage.php admin/roles/usersroles.php?userid=2&courseid=2 (This will redirect you to enrol in the course and not to login) You will also be logged in as a guest and will need to log in as a user and then log out to get back to the original logged out state) admin/tasklogs.php admin/timezone.php admin/tool/monitor/managerules.php admin/tool/oauth2/issuers.php admin/tool/task/scheduledtasks.php

      If you are not logged in and you deep link to almost any admin page, then instead of getting prompted to login, you instead get automatically logged in as a guest and then get an error. With debugging on it looks like this:

       
      Access denied

      More information about this error
      ×Debug info:
      Error code: accessdenied
      ×Stack trace: * line 496 of /lib/setuplib.php: moodle_exception thrown

      • line 7655 of /lib/adminlib.php: call to print_error()
      • line 12 of /admin/auth_config.php: call to admin_externalpage_setup()
         

      These should instead just send you directly to the login page as everyone would expect.
