titleIntroduction

Use this guide to enable Multi-Factor Authentication and Single Sign-on (SSO) access via encryption and web service to customer-controlled web applications.

Workflow:

1. End-users will be redirected (via browser) to SecureAuth IdP for authentication upon attempting access into the application without an internal session token or an encrypted string from SecureAuth

2. SecureAuth IdP will then authenticate the end-user, and send the encrypted authenticated User ID in a cookie, query string, or the header (options represented as token in Custom Application Configuration Steps) to the application following a successful authentication

3. The application will detect the encrypted string, extract it, and then contact the SecureAuth IdP web service to retrieve the User ID in plaintext

4. The application then uses the User ID to create an internal session token and to authorize the user into the application

titlePrerequisites

1. Have a custom web application and modification access

2. Enable the UserExchange Web Service

titleEnablement Steps

1. On the SecureAuth IdP appliance, open D:\SecureAuthWS\web.config

2. Locate the key, EnablePOC

3. Change the value of the key to 1

<add key="EnablePOC" value="1" />

3. Create a New Realm for the custom application integration in the SecureAuth IdP Web Admin

4. Configure the following tabs in the Web Admin before configuring the Post Authentication tab:

  • Overview – the description of the realm and SMTP connections must be defined
  • Data – an enterprise directory must be integrated with SecureAuth IdP
  • Workflow – the way in which users will access this application must be defined
  • Registration Methods / Multi-Factor Methods – the Multi-Factor Authentication methods that will be used to access this page (if any) must be defined
Info

The Registration Methods tab in SecureAuth IdP Version 9.0 has been renamed Multi-Factor Methods as of Version 9.0.1

titleCustom Application Configuration Steps

1. Change the application's Login Page to look for some type of internal session token

This will alert the application to allow access to end-users if it is present (bypassing additional authentication)

2. If there is no internal session token, have the Login Page look to see if there is a Token Name, eu (the cookie, query string, or header from SecureAuth IdP)

3. If there is no eu token, enable the redirection to the SecureAuth IdP URL, along with the ReturnURL as a query string

Example redirect URL: https://secureauth.company.com/secureauth2/?ReturnURL=https://app.company.com

The SecureAuth IdP URL will be the Fully Qualified Domain Name (FQDN) of the SecureAuth IdP appliance, followed by the SecureAuth IdP custom application-integrated realm (https://secureauth.company.com/secureauth2)

The ReturnURL will typically be the FQDN of the custom application

4. If there is an eu token, extract the value inside of the token

5. Make a web service call to retrieve the Authenticated User ID value by passing in the value of the eu token as input parameter to the function

A copy of the web service is located at the FQDN of the SecureAuth IdP appliance, followed by /SecureAuthWS/UserService.asmx, e.g. https://secureauth.company.com/SecureAuthWS/UserService.asmx

A copy of the WSDL for development is located at the FQDN of the SecureAuth IdP appliance, followed by /SecureAuthWS/UserService.asmx?WSDL, e.g. https://secureauth.company.com/SecureAuthWS/UserService.asmx?WSDL

The GetUserID takes one input parameter, the EncryptedUserString (the eu token value)

This will return the Decrypted Authenticated User ID as a String regardless of when the token was generated

The GetUserIDWithTimeCheck takes two input parameters, EncryptedUserString and ValiditySeconds

This will only return the Decrypted Authenticated User ID as a String if the token was generated within the validity time frame (e.g. 5 - 10 seconds)

6. Generate an internal session token, and take the Decrypted Authenticated User ID String and log the user into the application

7. (OPTIONAL) Clear the value inside the eu token so that it cannot be reused
