Apache Proxy to limit dashboards

Hello together,

i try to limiting the access to chosen dashboards. Is that possible?
The idea behind it is that employees only have the insight on a dashboard with anonymous access and not on multiple dashboards.
Client => Apache Proxy (other linux client) => Grafana-Server
Client access for example and get the this URL from the grafana-server:

Apache Proxy:

ErrorLog “logs/authproxy-error_log”
CustomLog “logs/authproxy-access_log” common
RewriteEngine on
RewriteRule ^/?$ /grafana/ [R=permanent,L]
<Location “/grafana”>
ProxyPass http:///
ProxyPassReverse /grafana http:///


protocol = http
http_port = 3000
domain =
root_url = %(protocol)s://%(domain)s:%(http_port)s/grafana/

But it shows me only the proxy failure side from grafana-server.
Has anyone ever tried the same?
