=== OpenID Connect v1.0 Identity Providers
|
|
|
|
{project_name} can broker identity providers based on the OpenID Connect protocol. These IDPs must support the <<_oidc, Authorization Code Flow>>
|
|
as defined by the specification in order to authenticate the user and authorize access.
|
|
|
|
To begin configuring an OIDC provider, go to the `Identity Providers` left menu item
|
|
and select `OpenID Connect v1.0` from the `Add provider` drop down list. This will bring you to the `Add identity provider` page.
|
|
|
|
.Add Identity Provider
|
|
image:{project_images}/oidc-add-identity-provider.png[]
|
|
|
|
The initial configuration options on this page are described in <<_general-idp-config, General IDP Configuration>>.
|
|
You must define the OpenID Connect configuration options as well. They basically describe the OIDC IDP you are communicating with.
|
|
|
|
.OpenID Connect Config
|
|
|===
|
|
|Configuration|Description
|
|
|
|
|Authorization URL
|
|
|Authorization URL endpoint required by the OIDC protocol
|
|
|
|
|Token URL
|
|
|Token URL endpoint required by the OIDC protocol
|
|
|
|
|Logout URL
|
|
|Logout URL endpoint defined in the OIDC protocol. This value is optional.
|
|
|
|
|Backchannel Logout
|
|
|Backchannel logout is a background, out-of-band, REST invocation to the IDP to logout the user. Some IDPs can only perform logout through browser redirects as they may
|
|
only be able to identity sessions via a browser cookie.
|
|
|
|
|User Info URL
|
|
|User Info URL endpoint defined by the OIDC protocol. This is an endpoint from which user profile information can be downloaded.
|
|
|
|
|Client ID
|
|
|This realm will act as an OIDC client to the external federation IDP you are configuring here. Your realm will need a OIDC client ID when using the Authorization Code Flow
|
|
to interact with the external IDP
|
|
|
|
|Client Secret
|
|
|This realm will need a client secret to use when using the Authorization Code Flow.
|
|
|
|
|Issuer
|
|
|Responses from the IDP may contain an issuer claim. This config value is optional. If specified, this claim will be validated against the value you provide.
|
|
|
|
|Default Scopes
|
|
|Space-separated list of OIDC scopes to send with the authentication request. The default is `openid`
|
|
|
|
|Prompt
|
|
|Another optional switch. This is the prompt parameter defined by the OIDC specification. Through it you can force re-authentication and other options. See the specification for
|
|
more details
|
|
|
|
|Validate Signatures
|
|
|Another optional switch. This is to specify if {project_name} will verify the signatures on the external ID Token signed by this Identity provider. If this is on,
|
|
the {project_name} will need to know the public key of the external OIDC identity provider. See below for how to setup it.
|
|
WARNING: For the performance purposes, {project_name} caches the public key of the external OIDC identity provider. If you think that private key of your Identity provider
|
|
was compromised, it is obviously good to update your keys, but it's also good to clear the keys cache. See
|
|
<<_clear-cache, Clearing the cache>> section for more details.
|
|
|
|
|Use JWKS URL
|
|
|Applicable if `Validate Signatures` is on. If the switch is on, then identity provider public keys will be downloaded from given JWKS URL.
|
|
This allows great flexibility because new keys will be always re-downloaded again when identity provider generates new keypair. If the switch is off,
|
|
then public key (or certificate) from the {project_name} DB is used, so when identity provider keypair changes, you always need to import new key to the {project_name} DB as well.
|
|
|
|
|JWKS URL
|
|
|URL where identity provider keys in JWK format are stored. See https://self-issued.info/docs/draft-ietf-jose-json-web-key.html[JWK specification] for more details.
|
|
If you use external {project_name} identity provider, then you can use URL like http://broker-keycloak:8180/auth/realms/test/protocol/openid-connect/certs assuming your brokered
|
|
{project_name} is running on http://broker-keycloak:8180 and it's realm is `test` .
|
|
|
|
|Validating Public Key
|
|
|Applicable if `Use JWKS URL` is off. Here is the public key in PEM format that must be used to verify external IDP signatures.
|
|
|
|
|Validating Public Key Id
|
|
|Applicable if `Use JWKS URL` is off. This field specifies ID of the public key in PEM format. This config value is optional. As there is no standard way
|
|
for computing key ID from key, various external identity providers might use different algorithm from {project_name}. If the value of this field
|
|
is not specified, the validating public key specified above is used for all requests regardless of key ID sent by external IDP. When set, value of this
|
|
field serves as key ID used by {project_name} for validating signatures from such providers and must match the key ID specified by the IDP.
|
|
|
|
|===
|
|
|
|
You can also import all this configuration data by providing a URL or file that points to OpenID Provider Metadata (see OIDC Discovery specification).
|
|
If you are connecting to a {project_name} external IDP, you can import the IDP settings from the url `<root>/auth/realms/{realm-name}/.well-known/openid-configuration`.
|
|
This link is a JSON document describing metadata about the IDP.
