SAML IdP metadata ingestion (to support SAML IdP certificate rotation) #983

Open srenatus opened 7 years ago

srenatus commented 7 years ago

Currently, the SAML connector is configured using either a hardcoded cert PEM file or data (that is read once when the connector is configured). IdP that rotate their signing keys publish the certs of their keys via metadata.

I saw that there's a TODO comment regarding metadata already -- What's the state of this? Is this on any roadmap?

I've also wondered how to do this in Dex. Would it be an acceptable thing to spawn a goroutine in the Open() method? Or would this be covered by #968, and an external process that polls the IdP's metadata and sets the certificate(s) to be used for signature verification?

Thanks! 😃

Hi @srenatus,

Currently the SAML metadata discovery is not on our roadmap but we hope that https://github.com/coreos/dex/issues/968 should handle this requirement. #968 will be picked up and worked soon.

@rithujohn191 thanks for the insights! :)

Btw, I believe there used to be a roadmap doc here -- Is this still something I could take a peek at somewhere?

Thinking about this again, it seems like the right approach would be to make the SAML connector more like an go-oidc client -- treating IdP metadata analogously to jwks here.

This would address the issue of the SAML IdP rotating their certificates periodically, and Dex's SAML connector keeping up with that -- instead of using hardcoded IdP certs.

Also: Is this something you'd accept as a PR?
