From version 1.9.0, Humio supports authenticating with any provider following the OpenID Connect standard. When OpenID Connect is configured, Humio accepts OpenID tokens issued by the OpenID Connect provider (Humio acts as a “resource” in OpenID Connect terms). This is useful if you are running Humio behind a proxy that handles authentication.
In addition to acting as a resource, Humio can also act as a client responsible for authenticating users (a “relying party” in OpenID Connect terms). This is similar to other OAuth authentication flows Humio supports.
The following parameters are necessary for running Humio as either a relying party or resource:
OIDC_PROVIDER— URL to the OpenID Connect provider. The provider URL must match the issuer reported by the OpenID provider exactly. Required.
OIDC_AUDIENCE— The audience to expect in a JWT. Defaults to the client ID if set and to “humio” otherwise.
OIDC_USERNAME_CLAIM— The name of the claim to interpret as username in Humio. The value in the claim must be a string. Defaults to
humio-user. Can be set to
OIDC_GROUPS_CLAIM— The name of the claim to interpret as the groups in Humio. The value in the claim must be an array of strings. Optional. Defaults to
OIDC_CACHE_USERINFO_MS— How long user info is cached on a Humio node in milliseconds. Optional. Defaults to 600000 (10 minutes).
Humio will use the OpenID Connect Discovery endpoint
%OIDC_PROVIDER%/.well-known/openid-configuration) to configure the remaining parameters
automatically. If your provider does not have such an endpoint, the following parameters must be
OIDC_AUTHORIZATION_ENDPOINT— A URL to the endpoint a user should be redirected to when authorizing. Required for clients.
OIDC_TOKEN_ENDPOINT— A URL to the token endpoint used to exchange a authentication code to an access token. Required for clients.
OIDC_USERINFO_ENDPOINT— A URL to the user info endpoint used to retrieve user information from an access token. Required.
OIDC_JWKS_URI— A URL to the JWKS endpoint for retrieving keys for validating tokens. Required.
To use OIDC as a client,
PUBLIC_URL must be set, Humio must be registered as a client with your
OpenID provider, and the provider must allow
%PUBLIC_URL%/auth/oidc as a valid redirect endpoint
for the client. The following parameters can be used to configure client setup
OIDC_OAUTH_CLIENT_ID— Client ID of your OpenID application. Required.
OIDC_OAUTH_CLIENT_SECRET— Client secret of your OpenID application. Required.
OIDC_SERVICE_NAME— The display name of the OIDC provider on the sign in page of Humio. Optional. Defaults to “OpenID Connect”.
