# Login failed for UserX with SQL

Wenn beim Versuch, sich mit der Datenquelle zu verbinden, der Fehlercode `(0x80131904): Login failed for user 'UserX'` erscheint, ist es möglich, dass das Konto nach mehreren Anmeldeversuchen gesperrt wurde. Dies hängt von der konfigurierten Durchsetzung der Passwortrichtlinie ab.

### Entsperren der SQL-Datenbank

Die folgende SQL-Abfrage bestätigt, ob der Benutzer gesperrt wurde:

`SELECT LOGINPROPERTY('UserX','islocked')`

Der Benutzer kann manuell entsperrt werden, indem Sie zu den Benutzer-***Eigenschaften*** – ***Status*** gehen und ***Lock SQL user*** deaktivieren. Ändern Sie anschließend das Passwort und führen Sie schließlich die Änderungen aus.

#### Alternative

Alternativ kann die folgende Abfrage verwendet werden:

`ALTER LOGIN [SQLID] WITH PASSWORD = '****' UNLOCK`

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.devolutions.net/rdm/de/knowledge-base/troubleshooting-articles/login-failed-for-userx-with-sql.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
