# OpenID Connect Provider Certification
|
||||||
|
|
||||||
|
The OpenID Foundation provides a set of [conformance test profiles][oidc-conf-profiles] that test both Relying Party and OpenID Provider (OP) OpenID Connect implementations. Upon submission of [results][oidc-result-submission] and an affirmative response, the affirmed OP will be listed as a [certified OP][oidc-certified-ops] on the OpenID Connect website and allowed to use the [certification mark][oidc-cert-mark] according to the certification [terms and conditions][oidc-terms-conds], section 3(d).
|
||||||
|
|
||||||
|
## Basic OpenID Provider Tests
|
||||||
|
|
||||||
|
Dex is an OP that strives to implement the [mandatory set][oidc-core-spec-mandatory] of OpenID Connect features, and can be tested against the Basic OpenID Provider profile ([profile outline][oidc-conf-profiles], section 2.1.1). These tests ensure that all features required by a [basic client][oidc-basic-client-spec] work as expected.
|
||||||
|
|
||||||
|
Features are currently under development to fully comply with the Basic profile, as dex currently does not. The following issues track our progress:

|
### Setup
|
||||||
|
|
||||||
|
There are two ways to set up an OpenID test instance:
|
||||||
|
1. Configure a test instance provided by The OpenID Foundation by following [instructions][oidc-test-config] on their website.
|
||||||
|
1. Download their test runner from [GitHub][oidc-github] and follow the instructions in the [README][oidc-github-readme].
|
||||||
|
* Requires `docker` and `docker-compose`
|
||||||
|
|
||||||
|
Configuration is essentially the same for either type of OpenID test instance. We will proceed with option 1 in this example, and set up an [AWS EC2 instance][aws-ec2-instance] to deploy dex:
|
||||||
|
* Create an [AWS EC2 instance][aws-ec2-quick-start] and connect to your instance using [SSH][aws-ec2-ssh].
|
||||||
|
* Install [dex][dex-install].
|
||||||
|
* Ensure whatever port dex is listening on (usually 5556) is open to ingress traffic in your security group configuration.
|
||||||
|
* In this example the public DNS name, automatically assigned to each internet-facing EC2 instance, is **my-test-ec2-server.com**. You can find your instances' in the AWS EC2 management console.
|
||||||
|
|
||||||
|
### Configuring an OpenID test instance
|
||||||
|
|
||||||
|
1. Navigate to [https://op.certification.openid.net:60000][oidc-test-start].
|
||||||
|
1. Click 'New' configuration.
|
||||||
|
1. Input your issuer url: `http://my-test-ec2-server.com:5556/dex`.
|
||||||
|
1. Select `code` as the response type.
|
||||||
|
1. Click 'Create' to further configure your OpenID instance.
|
||||||
|
1. On the next page, copy and paste the `redirect_uris` into the `redirectURIs` config field (see below).
|
||||||
|
1. At this point we can run dex, as we have all the information necessary to create a config file (`oidc-config.yaml` in this example):
|
||||||
|
```yaml
|
||||||
|
issuer: http://my-test-ec2-server.com:5556/dex
|
||||||
|
storage:
|
||||||
|
type: sqlite3
|
||||||
|
config:
|
||||||
|
file: examples/dex.db
|
||||||
|
web:
|
||||||
|
http: 0.0.0.0:5556
|
||||||
|
oauth2:
|
||||||
|
skipApprovalScreen: true
|
||||||
|
staticClients:
|
||||||
|
- id: example-app
|
||||||
|
redirectURIs:
|
||||||
|
- 'https://op.certification.openid.net:${OPENID_SERVER_PORT}/authz_cb'
|
||||||
|
name: 'Example App'
|
||||||
|
secret: ZXhhbXBsZS1hcHAtc2VjcmV0
|
||||||
|
connectors:
|
||||||
|
- type: mockCallback
|
||||||
|
id: mock
|
||||||
|
name: Example
|
||||||
|
```
|
||||||
|
* Substitute `OPENID_SERVER_PORT` for your OpenID test instance port number, assigned after configuring that instance.
|
||||||
|
* Set the `oauth2` field `skipApprovalScreen: true` to automate some clicking.
|
||||||
|
1. Run dex:
|
||||||
|
```bash
|
||||||
|
$ ./bin/dex serve oidc-config.yaml
|
||||||
|
time="2017-08-25T06:34:57Z" level=info msg="config issuer: http://my-test-ec2-server.com:5556/dex"
|
||||||
|
...
|
||||||
|
```
|
||||||
|
1. Input `client_id` and `client_secret` from your config file.
|
||||||
|
* The `id` and `secret` used here are from the example config file [`staticClients` field](../examples/config-dev.yaml#L50-L55).
|
||||||
|
1. Use data returned by the `GET /.well-known/openid-configuration` API call to fill in the rest of the configuration forms:
|
||||||
|
```bash
|
||||||
|
[home@localhost ~]$ curl http://my-test-ec2-server.com:5556/dex/.well-known/openid-configuration
|
||||||
|
{
|
||||||
|
"issuer": "http://my-test-ec2-server.com:5556/dex",
|
||||||
|
"authorization_endpoint": "http://my-test-ec2-server.com:5556/dex/auth",
|
||||||
|
"token_endpoint": "http://my-test-ec2-server.com:5556/dex/token",
|
||||||
|
"jwks_uri": "http://my-test-ec2-server.com:5556/dex/keys",
|

|
||||||

|
||||||
|
"email",
|
||||||
|
"groups",
|
||||||
|
"profile",
|
||||||
|
"offline_access"
|
||||||
|
],
|
||||||
|
"token_endpoint_auth_methods_supported": [
|
||||||
|
"client_secret_basic"
|
||||||
|
],
|
||||||
|
"claims_supported": [
|
||||||
|
"aud",
|
||||||
|
"email",
|
||||||
|
"email_verified",
|
||||||
|
"exp",
|
||||||
|
"iat",
|
||||||

|
||||||
|
"locale",
|
||||||
|
"name",
|
||||||
|
"sub"
|
||||||
|
]
|
||||||
|
}
|
||||||
|
```
|
||||||
|
* Fill in all configuration information that the `/.well-known/openid-configuration` endpoint returns, althgouh this is not strictly necessary. We should give the test cases as much information about dex's OP implementation as possible.
|
||||||
|
1. Press the 'Save and Start' button to start your OpenID test instance.
|
||||||
|
1. Follow the provided link.
|
||||||
|
1. Run through each test case, following all instructions given by individual cases.
|
||||||
|
* In order to pass certain cases, screenshots of OP responses might be required.
