| * MediaWiki allows **admin login** through OpenID by assigning the **group 'sysop'** in the group mapping. The 'groups' scope must be included in both Admidio's as well as MediaWiki's config, and Admidio's role must be included as an OIDC claim. | * MediaWiki allows **admin login** through OpenID by assigning the **group 'sysop'** in the group mapping.

| * By default, MediaWiki will use basic http authentication for its calls to the authorization and token endpoints, which means that no special characters (in particular colons) are allowed. Unfortunately, the client ID will be used as username, which typically contains a colon in 'https://...'. The OpenID specification states that the colon is the separator between username and passphrase (client secret), so Admidio will incorrectly assume 'https' to be the username and everything else is the client secret... The two possible solutions are to (1) either not use the full URL, but any other unique identifier without a colon as clientID, or (2) switch MediaWiki to the 'client_secret_post' authMethod in the MediaWiki's ''LocalSettings.php'' configuration file (see the example above, which already contains this fix). | * By default, MediaWiki will use basic http authentication for its calls to the authorization and token endpoints, which means that no special characters (in particular colons) are allowed.
