Token validation for multiple IdPs
You can verify tokens issued by multiple IdP using the extra_jwks_uris configuration option, with the following considerations:
- Since the plugin only accepts a single issuer, any
issclaim verification will fail for tokens that come from a different IdP than the one that was used in the issuer configuration option. Add all issuers as they appear in theissclaims of your tokens to theconfig.issuers_allowedsetting. - If you make any changes to the
extra_jwks_urisvalue, you have to clear the second level DB cache for the change to become effective. See Delete a Discovery Cache Object.
This example shows how to configure two different extra_jwks_uris to support token validation for two different IdPs.
Prerequisites
- A configured identity provider (IdP)
Environment variables
-
ISSUER: The issuer authentication URL for your IdP. For example, if you’re using Keycloak as your IdP, the issuer URL looks like this:http://localhost:8080/realms/example-realm -
CLIENT_ID: The client ID that the plugin uses when it calls authenticated endpoints of the IdP. -
CLIENT_SECRET: The client secret needed to connect to your IdP.
