i have tried to access grafana with Openid(auth), but i also want to access with saml2, now grafana5.x doesn’t seems to support it.some ideals about it? Or if i want to do this, how much work should i do? thanks.
You are right. Grafana doesn’t support SAML at the moment. So if you want to use it, then you have to code (Golang) it or you need to find another workaround (converter SAML<->OAuth).
Another no coding option can be Apache (reverse proxy mode) in front of Grafana (AuthProxy mode). Apache will be configured with SAML friendly module (Shibboleth, mellon, …), which will handle user auth.
