Disabled users throw constant fatal frror in logs: `ServiceUnavailable` + `LoginException`

[eppfel]

I deactivated a user on my installation and this is also the only deactivated user. Apparently a device of said user is still configured to sync and therefore tries to log in. The server log shows fatal errors. If this is standard behaviour, I think that is a bug. Deactivating a user is a standard procedure. Hence a login attempt is not an error. Maybe it justifies some debug / ingo logging, but not to throw an exception.

(And the german "Benutzer deaktiviert" does not belong there either. ^^)

I have the same issue. Reason, I do not want to have the user active nor do I want the user to be deleted. But also having "Fatal Errors" every few seconds in my logging is also not really an option, because I wouldn't see any "real" errors!

There shouldn't be errors for deactivated users

Is this Issue still valid in NC21.0.3? If not, please close this issue. Thanks! :)

This issue has been automatically marked as stale because it has not had recent activity and seems to be missing some essential information. It will be closed if no further activity occurs. Thank you for your contributions.

Still present in 21.0.4 :(
