HTTP server can be used to authenticate ClickHouse users. HTTP authentication can only be used as an external authenticator for existing users, which are defined in `users.xml` or in local access control paths. Currently, [Basic](https://datatracker.ietf.org/doc/html/rfc7617) authentication scheme using GET method is supported.
|
|
|
|
## HTTP authentication server definition {#http-auth-server-definition}
|
|
|
|
To define HTTP authentication server you must add `http_authentication_servers` section to the `config.xml`.
|
|
|
|
**Example**
|
|
```xml
|
|
<clickhouse>
|
|
<!- ... -->
|
|
<http_authentication_servers>
|
|
<basic_auth_server>
|
|
<uri>http://localhost:8000/auth</uri>
|
|
<connection_timeout_ms>1000</connection_timeout_ms>
|
|
<receive_timeout_ms>1000</receive_timeout_ms>
|
|
<send_timeout_ms>1000</send_timeout_ms>
|
|
<max_tries>3</max_tries>
|
|
<retry_initial_backoff_ms>50</retry_initial_backoff_ms>
|
|
<retry_max_backoff_ms>1000</retry_max_backoff_ms>
|
|
</basic_auth_server>
|
|
</http_authentication_servers>
|
|
</clickhouse>
|
|
|
|
```
|
|
|
|
Note, that you can define multiple HTTP servers inside the `http_authentication_servers` section using distinct names.
|
|
|
|
**Parameters**
|
|
- `uri` - URI for making authentication request
|
|
|
|
Timeouts in milliseconds on the socket used for communicating with the server:
|
|
- `connection_timeout_ms` - Default: 1000 ms.
|
|
- `receive_timeout_ms` - Default: 1000 ms.
|
|
- `send_timeout_ms` - Default: 1000 ms.
|
|
|
|
Retry parameters:
|
|
- `max_tries` - The maximum number of attempts to make an authentication request. Default: 3
|
|
- `retry_initial_backoff_ms` - The backoff initial interval on retry. Default: 50 ms
|
|
- `retry_max_backoff_ms` - The maximum backoff interval. Default: 1000 ms
|
|
|
|
### Enabling HTTP authentication in `users.xml` {#enabling-http-auth-in-users-xml}
|
|
|
|
In order to enable HTTP authentication for the user, specify `http_authentication` section instead of `password` or similar sections in the user definition.
|
|
|
|
Parameters:
|
|
- `server` - Name of the HTTP authentication server configured in the main `config.xml` file as described previously.
|
|
- `scheme` - HTTP authentication scheme. `Basic` is only supported now. Default: Basic
|
|
|
|
Example (goes into `users.xml`):
|
|
```xml
|
|
<clickhouse>
|
|
<!- ... -->
|
|
<my_user>
|
|
<!- ... -->
|
|
<http_authentication>
|
|
<server>basic_server</server>
|
|
<scheme>basic</scheme>
|
|
</http_authentication>
|
|
</test_user_2>
|
|
</clickhouse>
|
|
```
|
|
|
|
:::note
|
|
Note that HTTP authentication cannot be used alongside with any other authentication mechanism. The presence of any other sections like `password` alongside `http_authentication` will force ClickHouse to shutdown.

### Enabling HTTP authentication using SQL {#enabling-http-auth-using-sql}
|
|
|
|
When [SQL-driven Access Control and Account Management](/docs/en/guides/sre/user-management/index.md#access-control) is enabled in ClickHouse, users identified by HTTP authentication can also be created using SQL statements.
|
|
|
|
```sql
|
|
CREATE USER my_user IDENTIFIED WITH HTTP SERVER 'basic_server' SCHEME 'Basic'
|
|
```
|
|
|
|
...or, `Basic` is default without explicit scheme definition
|
|
|
|
```sql
|
|
CREATE USER my_user IDENTIFIED WITH HTTP SERVER 'basic_server'
|
|
```
|
|
|
|
### Passing session settings {#passing-session-settings}
|
|
|
|
If a response body from HTTP authentication server has JSON format and contains `settings` sub-object, ClickHouse will try parse its key: value pairs as string values and set them as session settings for authenticated user's current session. If parsing is failed, a response body from server will be ignored.
