Pass Through Authentication

Pass Through Authentication (PTA) lets a user go straight to the platform from an organization's web page or application, without having to log in again.

How it Works

While using an enterprise application, a user would like to visit a page hosted on the platform, without having to log in to the platform to see it (after having already logged in to the enterprise app). To accomplish that goal, the application sends a small SOAP message to the platform, in an HTTP request. That message contains the information needed to log into the platform. Data in it is passed to an authentication server, which sends back a message saying that authentication has succeeded or failed, after which the user is directed to the appropriate page, as shown in the following diagram:

Here is an explanation of the steps:

	User	Your Organization's Web App	Platform	Authentication Server
1.	Logs in to a web page or application provided by your organization
2.	Clicks a link that goes to a platform page
3.		Passes data to the platform's PTA service in the SOAP payload Session ID (optional, but desirable) Login ID
4.			Receives data in the SOAP payload: Passes data to the Authentication server
5.				Authenticates the user Sends back a success- or failure-report
6.			Redirects the user to the appropriate page.

Enabling Pass Through Authentication

The URL of the Authentication Server and the URLs of the pages to visit in the event of success or failure are configured in the platform's Single Sign-On Settings:

1. Go to > Administration > Company Setup > Single Sign-On
2. Click the [Edit] button
3. For Single Sign-On Settings, choose Pass Through Authentication
4. Fill in the Pass Through Authentication Settings:

   Third party Authentication Service URL

   Location of the authentication service. The platform uses this URL to authenticate the USER, passing the appropriate pay load in the HTTP request.

   Success page URL

   The page the platform sends the user to when authentication succeeds:

   • If not specified, the default destination is the platform's home page.

   Error page URL

   The page the platform sends the user to when authentication fails:

   • If not specified, the default destination is the platform’s Login-error page.
   • Can be overridden dynamically by the Authentication Server

5. Click [Save]

Message Formats

Posting a Form to the Platform

The application or web page can use a form like the one shown below to do an HTTP POST to the platform. The user is then seamlessly redirected to the success or failure page, depending on the results of the authentication.

<syntaxhighlight lang="xml" enclose="div">

<form id='testForm'

 action='https://{domain}/networking/passThroughAuth' 
 METHOD="POST" enctype="application/x-www-form-urlencoded"

>

 <input type="hidden" name="loginID" value="jondoe@test.com">
 <input type="hidden" name="sessionID" value="adasd3qw4q4weasdasd">

</form> </syntaxhighlight>

where:

loginID

The user's login name on the platform--typically in the form of an emails address.

sessionID

The session ID of the user on the organization's website. Optional. It is passed on to the authentication service, so the authentication service can make use of it.

Sending a SOAP Request to the Platform

This message format needs to be delivered to the platform by the Application or web page.

Method

POST

URI

https://{yourDomain}/networking/passThroughAuth

<syntaxhighlight lang="xml" enclose="div">

<?xml version="1.0" encoding="UTF-8" ?> <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"> <soapenv:Body> <LJAuthenticate xmlns="urn:authentication.soap.ws.longjump.com"> <sessionID>...</sessionID> <loginID>...</loginID> </LJAuthenticate> </soapenv:Body> </soapenv:Envelope> </syntaxhighlight>

where:

sessionID

The session ID of the user on the organization's website. Optional. It is passed on to the authentication service, so the authentication service can make use of it.

loginID

The user's login name on the platform--typically in the form of an emails address.

Messages Sent from the Platform to the Authentication Server

These message formats need to be processed and/or delivered by the Authentication Server.

Message sent from the platform to the Authentication Server

The platform passes on the request the Authentication Service.

The Authentication Service reads the form parameters (content type application/x-www-form-urlencoded)from the request and authenticates the user.

Method

POST

URI

Configured in the Single Sign-On Settings

<syntaxhighlight lang="xml" enclose="div">

<form id='testForm'

action='{authentication service URI}'
METHOD="POST" enctype="application/x-www-form-urlencoded"

   <input type="hidden" name="loginID" value="jondoe@test.com">
   <input type="hidden" name="sessionID" value="adasd3qw4q4weasdasd">
