User_ldap is missing in update 10.0.4

the user_ldap module is missing in the folder app/ since the update 10.0.4. I've also downloaded 10.0.4 manually to cross-check. did you remove this by purpose? how can i get it back? any client login is broken currently.

downloading the latest version from worked. but still the question remains why the app has been removed from the distribution...

The app was moved to the marketplace and is not bundled with the main tarball any more. This is to make it possible to update the app independently from core and provide faster updates.

I assume you upgraded from an OC version before OC 10. The occ upgrade should have given you hints about the need to manually install user_ldap from the marketplace.
