There is "No users were found" in Control Panel/Users and Organizations.
It is expected at least admin to be shown.
Adding the user is possible, all users are listed in site membership page. But access to user services from Control Panel is unavailable. User home pages also available.
The cleaning DB and Search re-indexing with following Liferay restart does not help.
The environment is vanilla DXP and CE installation, MySQL, Oracle JDK 1.8.
