Configuring Facebook as an Identity Provider
The EmpowerID SSO framework allows you to configure Facebook as an identity provider (IdP) for the EmpowerID Web application. EmpowerID integrates with Facebook using the OAuth protocol to allow your users to log in to EmpowerID using their Facebook accounts.
This topic describes how to configure an Identity Provider connection for Facebook and is divided into the following activities:
To add the Facebook AppID and AppSecret keys to the Facebook OAuth Connection
Adding MFA Points to the Facebook OAuth Connection
Adding a Login Tile for Facebook
Testing the Facebook Connection
As a prerequisite to creating an IDP Connection for Facebook, you must have a Facebook account and register the EmpowerID web application for your organization in the Facebook Developers Center. This creates a set of values known by Facebook and the EmpowerID web application that allow the two to trust one another. These values include the AppID and the App Secret (these values are generated by Facebook), as well as the OAuth redirect URI. (This value is entered by you to tell Facebook where to post the assertion of a user's identity to the EmpowerID Assertion Consumer Service).
For specific directions on registering EmpowerID as an application in Facebook, see the information provided by Facebook at https://developers.facebook.com.
When registering EmpowerID in Facebook, use the following URL as the valid OAuth redirect under Facebook Login Settings. Be sure to replace "FQDN_OF_YOUR_EMPOWERID_SERVER" with the FQDN or fully resolvable DNS of the EmpowerID Web server in your environment.
https://FQDN_OF_YOUR_EMPOWERID_SERVER/WebIdPForms/oauth/v2
Once the IDP Connection has been set up for Facebook, you can create a link similar to the one below to allow users to login to EmpowerID using Facebook. Be sure to replace "FQDN_OF_YOUR_EMPOWERID_SERVER" with the FQDN or fully resolvable DNS of the EmpowerID Web server in your environment and "Facebook" with the name of the IDP connection you create for Facebook in EmpowerID.
https://FQDN_OF_YOUR_EMPOWERID_SERVER/WebIdPForms/Login/Portal/Facebook?returnUrl=%2FWebIdPForms%2F
To add the App ID and App Secret
From the Navigation Sidebar of the EmpowerID Web interface, expand Admin, then SSO Connections, and click OAuth.
From the OAuth Applications management page, click the OAuth Service Provider tab and then search for Facebook.
From the OAuth Service Provider grid, click the Facebook link.
In the External OAuth Provider Details page that appears, in the grid at the bottom, click the Edit button for the specific Facebook connection you want to edit.
In the OAuth Connection pane that appears, in the Consumer Key field, type the APP ID Facebook generated for your application, and in the Consumer Secret field, type the App Secret.
Prepend the value of the Callback Url with the FQDN of your EmpowerID Web server, using the https scheme. For example, the FQDN of the EmpowerID Web server in our environment is "sso.empowersso.com" so the full Callback URL for our site is "https://sso.empowersso.com/webidpforms/oauth/v2."
Click Save to close the OAuth Connection pane.
Optionally, add any desired MFA points to the Facebook application by following the below steps.
To add MFA points to the Facebook application
From the External OAuth Providers page for Facebook, click the Provider Edit link at the top of the page.
In the MFA Point Value field, type the number of MFA points you want to give to users logging in with Facebook.
Click Save.
Next, add a login tile for Facebook to the desired IdP Domains. This allows your users to authenticate to EmpowerID with their Facebook credentials. If you have not set up an IdP Domain for your environment, you can do so by following the directions in the below drop-down.
To add a login tile for Facebook
From the Navigation Sidebar, expand Admin, then SSO Connections and click SSO Components.
Click the IdP Domains link for your domain.
In the IdP Domain Details page that appears, click the External OAuth Providers tab and check the box beside Facebook.
Click Save.
Now that the IDP Connection is configured, you can test it by following the below procedure.
To test the Facebook IDP Connection
From the Navigation Sidebar, expand IT Shop and click Workflows.
From the Workflows page, recycle the EmpowerID App Pools by clicking Recycle EmpowerID App Pools.
Log out of the EmpowerID Web interface and navigate your browser to the domain name you configured for the Facebook IdP connection, e.g. https://sso.empowersso.com.
Click the Login using Facebook button.
Log in to Facebook as you would normally do so.
Click Continue to allow EmpowerID to retrieve the information it needs to link your Facebook account to your EmpowerID identity (Person object).
Back in the EmpowerID Web application, click Yes to indicate that you have an EmpowerID login.
Type your EmpowerID Login or Email in the form and click Submit. The EmpowerID Person must have a valid email address as EmpowerID sends a one-time password to that address.
Check your email for the one-time password.
Back in the EmpowerID Web interface, type the one-time password into the Password field of the One-Time Password Validation form and click Submit.
