==== Google
|
|
|
|
There are a number of steps you have to complete to be able to login to Google. First, go to the `Identity Providers` left menu item
|
|
and select `Google` from the `Add provider` drop down list. This will bring you to the `Add identity provider` page.
|
|
|
|
.Add Identity Provider
|
|

|
|
|
|
You can't click save yet, as you'll need to obtain a `Client ID` and `Client Secret` from Google. One piece of data you'll need from this
|
|
page is the `Redirect URI`. You'll have to provide that to Google when you register {project_name} as a client there, so
|
|
copy this URI to your clipboard.
|
|
|
|
To enable login with Google you first have to create a project and a client in the https://console.cloud.google.com/project[Google Developer Console].
|
|
Then you need to copy the client id and secret into the {project_name} Admin Console.
|
|
|
|
NOTE: Google often changes the look and feel of the Google Developer Console, so these directions might not always be up to date and the
|
|
configuration steps might be slightly different.
|
|
|
|
Let's see first how to create a project with Google.
|
|
|
|
Log in to the link:https://console.cloud.google.com/project[Google Developer Console].
|
|
|
|
.Google Developer Console
|
|

|
|
|
|
Click the `Create Project` button.
|
|
Use any value for `Project name` and `Project ID` you want, then click the `Create` button.
|
|
Wait for the project to be created (this may take a while). Once created you will be brought to the project's dashboard.
|
|
|
|
.Dashboard
|
|

|
|
|
|
Then navigate to the `APIs & Services` section in the Google Developer Console. On that screen, navigate to `Credentials` administration.
|
|
|
|
When users log into Google from {project_name} they will see a consent screen from Google which will ask the user
|
|
if {project_name} is allowed to view information about their user profile. Thus Google requires some basic information about the product before creating any secrets for it. For a new project, you have first to configure `OAuth consent screen`.
|
|
|
|
For the very basic setup, filling in the Application name is sufficient. You can also set additional details like scopes for Google APIs in this page.
|
|
|
|
.Fill in OAuth consent screen details
|
|

|
|
|
|
The next step is to create OAuth client ID and client secret. Back in `Credentials` administration, navigate to `Credentials` tab and select `OAuth client ID` under the `Create credentials` button.
|
|
|
|
.Create credentials
|
|
image:images/google-create-credentials.png[]
|
|
|
|
You will then be brought to the `Create OAuth client ID` page. Select `Web application` as the application type. Specify the name you want for your client. You'll also need to
|
|
copy and paste the `Redirect URI` from the {project_name} `Add Identity Provider` page into the
|
|
`Authorized redirect URIs` field. After you do this, click the `Create` button.
|
|
|
|
.Create OAuth client ID
|
|
image:images/google-create-oauth-id.png[]
|
|
|
|
After you click `Create` you will be brought to the `Credentials` page. Click on your new OAuth 2.0 Client ID to view
|
|
the settings of your new Google Client.
|
|
|
|
.Google Client Credentials
|
|
image:images/google-client-credentials.png[]
|
|
|
|
|
|
You will need to obtain the client ID and secret from this page so you can enter them into the {project_name} `Add identity provider` page.
|
|
Go back to {project_name} and specify those items.
|
|
|
|
One config option to note on the `Add identity provider` page for Google is the `Default Scopes` field.
|
|
This field allows you to manually specify the scopes that users must authorize when authenticating with this provider.
|
|
For a complete list of scopes, please take a look at https://developers.google.com/oauthplayground/ . By default, {project_name}
|
|
uses the following scopes: `openid` `profile` `email`.
|
|
|
|
If your organization uses the G Suite and you want to restrict access to only members of your organization,
|
|
you must enter the domain that is used for the G Suite into the `Hosted Domain` field to enable it.
