Configuring OpenID authentication | HCL Digital Experience

Identity providers include sites such as, but not limited to, Google, Yahoo, and Facebook. As an Administrator, you can select how to configure authentication to work with these identity providers.

Before you begin

Set your system time to match your local time.

About this task

Users can always register and log in with HCL Digital Experience credentials. With the enable-identityprovider-tai task, you can choose between the following configurations:

Remember: Google and Yahoo are known identity providers that use OpenID specifications. Facebook uses OAuth.

Limitation: If you configure portal to use OpenID authentication with YAHOO as the identity provider, attribute exchange does not work. This limitation means that user attributes from your YAHOO OpenID account are not transferred to your portal user account.

Configure Facebook only, use the parameters that are designated as Facebook
Configure OpenID only, use the parameters that are designated as OpenID
Configure Facebook and OpenID, use the parameters that are designated as Facebook and OpenID

Procedure

If you plan to configure Facebook, register your HCL Digital Experience server instances as Facebook applications. You must register two applications. One application is the protected path: /wps/myportal. One application is the public, unprotected path: /wps/portal.

After you register, Facebook provides you with an application ID and an application secret. Use this information when you run the enable-identityprovider-tai task.

Tip: Your Facebook application has a private and public URL. The private URL is http://yourserver:yourport/wps/myportal/. The public URL is http://yourserver:yourport/wps/portal/.
Required: Run the following task from the wp_profile_root\ConfigEngine directory with the appropriate parameters:
Cluster note: Complete this step only on the primary node.
CAUTION: If you rerun the enable-identityprovider-tai task, the task sets new properties and does not preserve the old configuration data. If you want to keep the existing data, you must add the new values to the existing values before you rerun the task.
- AIX®: ./ConfigEngine.sh enable-identityprovider-tai -DWasUserId=username -DWasPassword=password
- HP-UX: ./ConfigEngine.sh enable-identityprovider-tai -DWasUserId=username -DWasPassword=password
- IBM® i: ConfigEngine.sh enable-identityprovider-tai -DWasUserId=username -DWasPassword=password
- Linux™: ./ConfigEngine.sh enable-identityprovider-tai -DWasUserId=username -DWasPassword=password
- Solaris: ./ConfigEngine.sh enable-identityprovider-tai -DWasUserId=username -DWasPassword=password
- Windows™: ConfigEngine.bat enable-identityprovider-tai -DWasUserId=username -DWasPassword=password
Add the following parameters to customize the task for your business requirements:

-Didp.providerlist

Set the value to facebook,openid if you want to configure both options. Set the value to facebook to configure Facebook only. Set the value to openid to configure only identity providers that use the OpenID specifications. If you leave this field blank, the default value is facebook.

-Dfacebook_apps

If you are configuring Facebook, you can use Facebook for authentication (app), self enrollment (pub), or both (app,pub). The default value is app. Set the value to one of the following values:

app

Configures authentication only.

pub

Configures self enrollment only.

app,pub

Configures both authentication and self enrollment.

-Dfacebook_app_id

If you are configuring Facebook for authentication, set the value to yourprivatefacebookappid, which you received when you registered your Portal server as a private Facebook application. This value is for your private URL.

-Dfacebook_app_secret

If you are configuring Facebook for authentication, set the value to yourprivatefacebookappsecret, which you received when you registered your Portal server as a private Facebook application. This value is for your private URL.

-Dfacebook_app_site

If you are configuring Facebook for authentication, set the value to http://yourserver:yourport/wps/myportal/. This value is the URL for your private HCL Digital Experience server that Facebook uses after a successful authentication. A protected area requires authentication to access and is not available to an anonymous user.

-Dfacebook_pub_id

If you are configuring Facebook for self enrollment, set the value to yourpublicfacebookappid, which you received when you registered your Portal server as a Facebook application. This value is for your public URL.

-Dfacebook_pub_secret

If you are configuring Facebook for self enrollment, set the value to yourpublicfacebookappsecret, which you received when you registered your Portal server as a Facebook application. This value is for your public URL.

-Dfacebook_pub_site

If you are configuring Facebook for self enrollment, set the value to http://yourserver:yourport/wps/portal/. This value is the URL for your public HCL Digital Experience server that Facebook uses after a successful authentication. A public area does not require authentication to access and is available to an anonymous user.

-Dopenid.servicenames

If you are configuring identity providers that use the OpenID specifications, enter a comma-separated list of the identity providers that you want configured; for example: Google,Yahoo.

-Dopenid.servicenames.endpoints

If you are configuring identity providers that use the OpenID specifications, enter a comma-separated list of OpenID endpoints (access addresses). These endpoints are for the identity providers in the openid.servicenames parameter. For example, type https://www.google.com/accounts/o8/id,https://me.yahoo.com/. There must be a one-to-one correspondence between the openid.servicenames and the openid.servicenames.endpoints parameters. If you entered three identity providers in the openid.servicenames parameter, you must enter three endpoints in the openid.servicenames.endpoints parameter and in the same sequence.

-Dprovider.openid.nonce_valid_time

If you are configuring identity providers that use the OpenID specifications, enter a value in seconds to protect old communications from being reused in replay attacks. If this parameter is not set, you might have nonce errors in your SystemOut.log file.
