Howto: webseal authentication in front of grafana

hi ,

I trying to integrate Webseal SSO to perform authentication with grafana. According to the grafana “Grafana Authproxy” tutorial, do i still need to run a apache webserver in between webseal and grafana?

http://docs.grafana.org/tutorials/authproxy/

regards

Does not need to be apache but any reverse proxy that can do the authentication and add the HTTP header.

was wondering which authentication to be used in the case?
I was trying to get [auth.proxy] to work, with the following setting

[auth.proxy]
enabled = true
header_name = http_username
header_property = username
auto_sign_up = true
ldap_sync_ttl = 60
whitelist =

am i using the right authentication?
