+Feature: As a teacher I can set availability dates restriction to an activity and see a warning when conflicting dates are set
+
+  Background:
+    Given the following "courses" exist:
+      | fullname | shortname | format | enablecompletion |
+      | Course 1 | C1        | topics | 1                |

- * key information for users - firstname, lastname, email.
+ * OAuth 2 issuer for linkedin which is mostly OIDC compliant, with a few notable exceptions which require working around:
+ *
+ * 1. LinkedIn don't provide their OIDC discovery doc at {ISSUER}/.well-known/openid-configuration as the spec requires.
+ * i.e. https://www.linkedin.com/.well-known/openid-configuration isn't present.
+ * Instead, they make the configuration available at https://www.linkedin.com/oauth/.well-known/openid-configuration.
+ * See: https://openid.net/specs/openid-connect-discovery-1_0.html#ProviderConfig
+ *
+ * 2. LinkedIn don't return 'locale' as a string in the userinfo but instead return an object with 'language' and 'country' props.
+ * See: https://openid.net/specs/openid-connect-core-1_0.html#StandardClaims
+ * This is resolved in {@see \core\oauth2\client\linkedin::get_userinfo()}
