I have a case where a customer noticed that when a User Federation provider is broken (ldap is down, ldap cert is not in the truststore, etc), the local user accounts cannot be accessed / viewed in the Admin console.
This issue appears to be related to KEYCLOAK-2984. However, KEYCLOAK-2984 is more about creating users while the User Federation provider is broken.
The customer would like to have the ability to view/manage local users while a user federation is down.
In my testing, when my ldap user federation provider is configured wrong or ldap is down and I click on "View all users", I get a red box with the following error:
Error! An unexpected server error has occurred
and no users (local or ldap) show up in the list. The user list is empty.
I am able to login as the local users, but "View all" does not work.
Recreated the issue on 7.1.0 and 7.1.1.
