OAuth 2.0 Auth Module
An OAuth 2.0 authentication module lets users log in to Hub and any connected services with credentials that are stored in an external authorization service. Hub provides pre-configured authentication modules for Amazon, Azure AD 2.0, Bitbucket Cloud, Facebook, GitLab, Microsoft Live, PayPal, and Yandex Passport.
Use the generic OAuth 2.0 authentication module to let users log in to Hub with accounts from other third-party services that support OAuth 2.0, like Basecamp, Stack Exchange, and Zendesk.
When you enable an OAuth 2.0 authentication module in Hub:
Your users log in to Hub with the credentials they use in an external service.
Your Hub users have fewer accounts and passwords to remember.
New users with accounts in the connected service can create their own accounts in Hub.
Enable OAuth 2.0 Authentication
To allow users with existing accounts in an external authorization service to log in to Hub, enable an OAuth 2.0 authentication module.
This procedure takes place in three steps:
Generate a Redirect URI in Hub. When you create an authentication module, Hub generates a redirect URI to use with the authorization service. This URI identifies the source of each login request.
Generate a Client ID and Secret in the authorization service. Every login request sent from Hub includes a unique identifier. The ID and secret you store in the authentication module tell the authorization service that each login request is authorized.
Enable the Auth Module in Hub. When you have generated the information Hub uses to authenticate with the authorization service, copy the values into Hub and enable the module.
Generate a Redirect URI in Hub
First, create the OAuth 2.0 authentication module. When you perform this action, Hub generates a redirect URI to use with the authorization service.
To generate a redirect URI in Hub:
In the Access Management section of the Administration menu, select .
From the New Module drop-down list, select OAuth 2.0.
The New OAuth 2.0 Module dialog opens.
Enter the Name and Authorization URL, then click the Create button.
The Auth Modules page displays the settings for a new OAuth 2.0 authentication module.
Hub generates a redirect URI for you to use in the authorization service.
If the feature is supported by your browser, use the Copy button to copy the redirect URI to your clipboard.
Make sure to update the Redirect URI in the authorization service when you change the base URL of your Hub instance. For example, after migrating data to another Hub service or changing proxy settings.
Generate a Client ID and Secret in the Authorization Service
The next step is to register the authorized redirect URI for Hub in the authorization service. This process varies by service. You can refer to the setup instructions for any of the pre-configured authentication modules, like Amazon, Azure AD 2.0, Bitbucket Cloud, Facebook, GitLab, Microsoft Live, PayPal, and Yandex Passport. The procedures for other third-party authorization services are similar.
Enable the Auth Module in Hub
To complete the setup, store the client ID and secret from the authorization service in the OAuth 2.0 auth module.
Copy the client ID from the authorization service and paste it into the Client ID input field in Hub.
Copy the client secret from the authorization service and paste it into the Client secret input field in Hub.
Configure the optional settings for the authentication module. For more information, see Additional Settings.
Click the Enable module button.
The OAuth 2.0 authentication module is enabled.
The icon stored in the Button image setting is added to the login dialog window. Users can click this icon to log in to Hub with an account from the connected authorization service.
Settings
The first section of the settings page displays the general settings for the authentication module. Here, you also find the redirect URI that you use to register Hub in the authorization service and the input fields that store the Client ID and Client Secret that are generated in the authorization service.
Setting | Description |
|---|---|
Type | Displays the type of authorization service that is enabled for third-party authentication in Hub. |
Name | Stores the name of the authentication module. Use this setting to distinguish this module from other authentication modules in the Auth Modules list. The name is also shown in the tooltip for the third-party service icon on the login form. |
Button image | Displays the image used for the button that a user clicks to log in to Hub with a their account in the connected authorization service. You can upload a JPG, GIF or PNG file. The image is resized to 48 x 48 pixels automatically. |
Redirect URI | Displays the authorized redirect URI that is used to register the connection to Hub in the authorization service. |
Client ID | Stores the identifier that the authorization service uses to validate a login request. You generate this value in the authorization service when you configure the authorization settings for a web application and enter an authorized redirect URI. |
Client Secret | Stores the secret or password used to validate the client ID. You generate this value in the authorization service together with the client ID. |
Authorization Service Endpoints
The settings in this section of the page store the OAuth 2.0 endpoints used by the authorization service. Additional settings let you define the request scope, and choose how to authenticate with the service.
For pre-configured OAuth 2.0 modules, the values that are used by the selected authorization service are set automatically.
Setting | Description |
|---|---|
Authorization | Stores the endpoint that Hub uses to obtain authorization from the resource owner via user-agent redirection. |
Token | Stores the endpoint that Hub uses to exchange an authorization grant for an access token. |
User data | Stores the endpoint used to locate profile data for the authenticated user. |
The endpoint used to locate the email address of the authenticated user Use only when the email address is not stored in the user profile | |
Default email verification state | Determines which state should be set for an email address in Hub, when the authentication service does not return the verification status for an email address. |
Field Mapping
When a user profile response object is returned by the authorization service, values from the specified field paths are copied to the user profile in Hub. Use the following settings to define the endpoint that locates profile data for the authenticated user and map fields that are stored in the authorization service to user accounts in Hub.
For pre-configured OAuth 2.0 modules, the values that are used by the selected authorization service are set automatically.
Use a sequence of path segments separated by slashes (/) to specify a path to a field inside a nested object.
Field | Description |
|---|---|
User ID | Maps to the field that stores the value to copy to the User ID property in Hub. |
Maps to the field that stores the value to copy to the Email field in the Hub profile. | |
Verified email | Maps to the field that stores the value to copy to the verified email property in Hub. |
Full name | Maps to the field that stores the value to copy to the Full name field in the Hub profile. |
Avatar | Maps to the field that stores the image to use as the Avatar in the Hub profile. |
Image URL pattern | Generates an image URL for avatars that are referenced by an ID. Use the <picture-id> placeholder to reference the field that stores the avatar. |
Scope | Sets the scope for the access request. Enter a list of scopes, separated by spaces. |
Authentication | Determines how credentials are passed to the authorization service. |
Additional Settings
The following options are located at the bottom of the page. Use these settings to manage Hub account creation and group membership, and to reduce the loss of processing resources consumed by idle connections.
Option | Description |
|---|---|
User creation | Enables creation of Hub accounts for unregistered users who log in with an account that is stored in the connected authorization service. Hub uses the email address to determine whether the user has an existing account. |
Auto-join groups | Adds users to a group when they log in with an account that is stored in the connected authorization service. You can select one or more groups. New users that auto-join a group inherit all of the permissions assigned to this group. |
Connection timeout | Sets the period of time to wait to establish a connection to the authorization service. The default setting is 5000 milliseconds (5 seconds). |
Read timeout | Sets the period of time to wait to read and retrieve user profile data from the authorization service. The default setting is 5000 milliseconds (5 seconds). |
Audit | Links to the Audit Events page in Hub. There, you can view a list of changes that were applied to this authentication module. |
