When migrating to namespaces, this class had to change its name, as "Default" is a reserved keyword. However, that implies changing the file name as well. Currently, it doesn't load.

When externalizing the modules, we started to 'require' for example ext-krb5, where we used to only 'suggest' it.
That's when AppVeyor started to fail, since those extensions are not available and have proven to be hard to install..
This workaround should do the trick until we stop including those externalized modules in releases.

Properly set NameIDFormat on generation

Downgrade externalized modules to a version that doesn't hold BC-breaking Webmozart-assertions
