Plugin does not pass X-Grafana-User http header even when grafana enable it #1451
Description
What happened:
Hi
I've tried enabling [dataproxy] send_user_header = true and use Forward Grafana HTTP Headers toggle in the datasource settings. Connected to a server that dumps all http headers - no X-Grafana-User header, when i try the same with Altinity plugin - it works. If i try to enable/disable send_user_header parameter - it appear/disappear from Altinity plugin requests.
Here is an example of Clickhouse plugin headers:
echo-server-1 | 2025-11-21T07:26:40.301Z Headers {
echo-server-1 | host: '10.1.0.249:8080',
echo-server-1 | 'user-agent': 'grafana/12.2.1 clickhouse-datasource/4.11.2 clickhouse-go/2.40.3 (lv:go/1.24.7; os:linux)',
echo-server-1 | 'content-length': '55',
echo-server-1 | 'accept-encoding': 'gzip',
echo-server-1 | authorization: 'Basic bmFtZTpwdw=='
echo-server-1 | } /?client_protocol_version=54460&database=analytics&default_format=Native&limit=1000000&max_execution_time=14
What you expected to happen:
X-Grafana-User header should present on http request to clickhouse from grafana
How to reproduce it (as minimally and precisely as possible):
Basic grafana config:
data:
grafana.ini: |
[server]
protocol = http
[dataproxy]
send_user_header = true
[users]
allow_sign_up = false
[auth]
disable_login_form = true
[auth.proxy]
enabled = true
header_name = X-AUTH-REQUEST-EMAIL
header_property = email
headers_encoded = false
auto_sign_up = true
sync_ttl = 0
Create new datasource, connect to HTTP Clickhouse.
Test data-source, see headers in the proxy
Screenshots
Anything else we need to know?:
Tried both HTTP and HTTPS versions, tried to use the data-source in the dashboard - results are the same, no header in the request
Environment:
- Grafana version: Grafana v12.2.1 (563109b696)
- Plugin version: 4.11.2
