Declaration of auth_plugin_authshibboleth::trustExternal() must be compatible with dokuwiki\Extension\AuthPlugin::trustExternal($user, $pass, $sticky = false)

[andrea-janna]

I'm using Dokuwiki version 2022-07-31b "Igor".

When I enable 'authshibboleth' authentication the following error is displayed in the browser instead of the wiki pages:
"dokuwiki\Exception\FatalException: Declaration of auth_plugin_authshibboleth::trustExternal() must be compatible with dokuwiki\Extension\AuthPlugin::trustExternal($user, $pass, $sticky = false)".

So I modified the file plugins/authshibboleth/auth.php replacing the line "public function trustExternal()" with "public function trustExternal($user, $pass, $sticky = false)".
I've been running the wiki for a few days since that and it seems that the issue is fixed.
