4 Overview By default Juniper SSL VPN logons requires that a user provide a correct user name and password to successfully logon. This document describes the steps necessary to augment this logon mechanism with strong authentication by adding a requirement to provide a one-time password generated by a CRYPTOCard token using the implementation instructions below. This document will also describe how to add SSO for OWA. Applicability This integration guide is applicable to: Security Partner Information Security Partner Juniper Networks Product Name and Version SA 700 / 6.2R1 (build 13255) Protection Category SSL Remote Access CRYPTOCard Server Authentication Server Version BlackShield ID Small Business Edition 1.2+ Professional Edition 2.3+ Assumptions 1. BlackShield ID has been installed and configured and a Test user account can be selected in the Assignment Tab. 2. BlackShield ID NPS IAS Agent has been installed and configured on the NPS IAS Server to accept RADIUS authentication from the Juniper SSL VPN. Operation This document provides step by step instruction on how to configure the Juniper SSL VPN to send RADIUS authentication to an external RADIUS Server.

5 Preparation and Prerequisites 1. Verify that a Test user account with a static password, can successfully authenticate via the Juniper SSL VPN 2. Ensure that Ports 1812 UDP and 1813 UDP are open to the NPS / IAS Server 3. The NPS IAS Agent must be configured to use either port 80 or port 443 to send authentication requests to the BlackShield ID server. 4. Ensure that you add a condition in IAS under Remote Access Policies. In the Remote Access Policies right click Authenticate to BlackShield and select Properties. Click Edit Profile and select the Advanced tab. Add an Attribute named Filter-Id with the value of CCUser1. Apply the changes and restart IAS. 5. Create or define a Test account that will be used to verify that the Juniper SSL VPN has been properly installed and configured. Verify that this account can successfully authenticate using a standard password before attempting to apply changes and test authentication using a token. Ensure that the user name for this account exists in BlackShield ID by locating it in the Assignment Tab. Configuration Adding the RADIUS Server To add a new RADIUS Server, click Auth Servers.

8 In the General tab of the User Realm add the Active Directory Authentication as the first server. Check Additional authentication server and add the RADIUS authentication. Beside Username is: check predefined as: and enter <USERNAME>. Do not leave it as <USER>. Edit the Default Sign-In Page or the page that you are using so that the Secondary password reads OTP.

9 In Resource Profiles / Web add a new Profile for OWA. Make sure in to add the Users in the Roles tab. In the Exchange System Manager uncheck Enable Forms Based Authentication. The SSO will not work with Forms Based Authentication. Edit the Default Sign-In Page or the page that you are using so that the Secondary password reads OTP.

10 Testing CRYPTOCard Authentication The next step is to test the new configured CRYPTOCard Two Factor Authentication. Open up a web browser and go to Enter in your username, Active Directory password and a CRYPTOCard generated Passcode Click Sign In If you successfully authenticate, then the following screen should appear.

11 Troubleshooting Failed Logons Symptom: Login Failed Indication: 11/19/ :36:49 PM Henry Authentication Failure Invalid OTP Possible Causes: Solution: The One Time Password provided for the user is incorrect. Attempt to re-authenticate against BlackShield again. If it comes up as invalid OTP again, test the token out via the BlackShield ID Manager. Symptom: Login Failed Indication: 11/19/ :47:24 PM Henry Authentication Failure Invalid PIN Possible Causes: Solution: The PIN provided for the user is incorrect. Attempt to re-authenticate against BlackShield again. If it comes up as invalid PIN again, changing the initial PIN back to default and forcing a PIN change would solve the issue, or have the user access the BlackShield Self Service page.
