= Overview =

Swivel can be integrated with the SA series of SSL VPN products, with the SA 2000 and higher products also allowing additional login page functionality. Creating additional login pages allow different authentication methods and test pages to be created with different functionality. Swivel can provide Two Factor authentication with [[SMS]], [[Token]], [[Mobile Phone Client]] and strong Single Channel Authentication [[TURing]], [[Pinpad]] or in the [[Taskbar How to Guide | Taskbar]] using RADIUS.

The SA 700 can be configured in a similar manner using RADIUS authentication except for the TURing image and other login page modifications.

For 6.x integration guide see [[Juniper SA 6.x Integration]]

For 7.x integration guide see [[Juniper SA 7.x Integration]]

It is also possible to configure Two Stage authentication whereby the user enters a username and AD Password and if correct the user can be sent a security string or OTC for Authentication. This can be combined with the Juniper Two Stage authentication to allow the AD Single Sign On (SSO) features. See [[Juniper Two Stage Challenge and Response]].


= Prerequisites =

Juniper 8.x

Swivel 3.x

Modified login pages can be downloaded below. Note that you don't need the included image files unless you are using [[Pinpad]].

It is possible to access Juniper SSL VPN from all mobile devices, however additional pages need to be modified to support Swivel integration.

Mobile login pages can be downloaded below, and should be included if the Single channel images are required on mobile devices. NOTE: These have not been tested on version 8.

Where the Virtual DNS is to be used, a DNS entry that uses the same IP address of the external VPN is required. For example turing.swivelsecure.com would need to point to the same IP address as vpn.swivelsecure.com. Since the Juniper will be supporting at least two different host names, the SSL certificate on the Juniper must either be a wildcard certificate, or must include SANs (Subject Alternative Names) for all host names used.

[https://kb.swivelsecure.com/wiki/images/a/a6/JuniperV8Combined.zip Modified pages for both PC and tablets]. These files have been tested internally only, and do not currently work with PINpad on tablets. The main advantage is that you only need edit one file - swivel-header.thtml - to set the image URL for all devices.

= Baseline =

Juniper 8

Swivel 3.9.7


= Architecture =

A user receives their security string by their transport and enters the authentication information into the login page. The Juniper makes a RADIUS request against the Swivel server to verify the OTC. Usually the Juniper page also verifies the AD password is correct by verifying it against the AD server, in addition to the OTC.


= Installation =

== Swivel Configuration ==

=== Configuring the RADIUS server ===

On the Swivel Administration console configure the RADIUS Server and NAS, see [[RADIUS Configuration]]


=== Enabling Session creation with username ===

To allow the [[TURing]] image, [[Pinpad]] and other single channel images, under Server/Single Channel set [[Allow session request by username]] to Yes.


== Setting up Swivel Dual Channel Transports ==

Used for [[SMS]], see [[Transport Configuration]]


== Juniper Integration ==

=== RADIUS Authentication Server Configuration ===

On the Juniper Server select Authentication Servers then select RADIUS Server from the drop down menu, and click on New Server. 


[[Image:RADIUS Authentication Server.jpg]]


The following information is required:

'''Name:''' A descriptive name for the RADIUS server

'''RADIUS Server:''' The Swivel server IP/Hostname (Use the Swivel server real IP address not the VIP, multiple servers can be defined as Primary and secondary servers).

'''Authentication Port:''' the port used to carry authentication information, by default 1812

'''Shared Secret:''' The shared secret that has been entered on the Swivel server

'''Accounting Port:''' the port used to carry accounting information, by default 1813

'''NAS-IP Address:''' the Juniper interface used for communication, usually left empty

'''Users authenticate using tokens or one-time passwords''' Ensure this box is ticked


Backup server, Enter the details of any additional Swivel servers which can be used for authentication.


[[Image:RADIUS Authentication Server page.jpg]]


=== Authentication Realm Configuration ===

Authentication realms determine which method of authentication will be used. On the Juniper select User Realms, and either create a new Realm with the New button or or modify an existing realm by clicking on it.


[[Image:User Realm.jpg]]


=== Swivel as the Primary Authentication Server ===


Swivel can be configured as the only authentication method, the first or more usually configured as the secondary authentication server. By changing the Authentication device order on the Juniper, Swivel can be configured as the first authentication server, but you may lose some functionality of SSO to sign you into AD applications and services. The login page would also need to be modified to display the correct text.

To configure Swivel as the server select the Swivel server as the first listed Authentication Server.


[[Image:Authentication realm.jpg]]


=== Swivel as the Secondary Authentication Server ===

Swivel can be configured as the only authentication method, or more usually configured as the secondary authentication server.

To configure Swivel as the server as a secondary authentication server cluck on the box '''Additional authentication server'''


[[Image:Authentication using two servers.jpg]]


Note when USERNAME is used then just the username is sent to the Juniper. When USER is used then the domain name may be added in the authentication request to the Swivel instance in the form domain\username.


USERNAME

[[Image:Juniper 7 Authentication server username is username.jpg]]

USER

[[Image:Juniper 7 Authentication server username is user.jpg]]


[[Image:User Realm PINsafe Realm.jpg]]


=== Juniper Sign-In Policy ===

The Policy associates a login URL to a login page and an authentication realm which will verify a users credentials. Swivel authentication can be applied to an existing authentication page or to a new possibly customised login page (see login page customisation).

To associate Swivel authentication to a signing in page, associate the realm with the required login page. On the Juniper select Signing-In/Sign-in Policies, then New URL. 


[[Image:Juniper sign in policies.jpg]]


Enter a name for the URL, and select a signing-in page (see details below for custom pages). Ensure Swivel is selected as an authentication realm.


[[Image:Juniper New sign in policy.jpg]]


When complete the new Swivel policy should be listed.


[[Image:Juniper new sign in policy pinsafe.jpg]]


= Additional Installation Options =

Swivel can provide additional authentication options including:

[[Juniper Two Stage Challenge and Response How To | Challenge and Response]]

Single Channel Authentication Images

Dual Channel Image for Confirmed Messages

Security String Index Image for Multiple security strings

For ChangePIN integration see [[Juniper ChangePIN]]


Where an image is used it is requested by the client from the Swivel server, this can be done in a number of ways:

*Swivel on a public IP address

*Swivel behind a Network Address Translation/Port Address Translation

*Swivel behind a Proxy server

*Swivel behind a Juniper Virtual DNS Proxy


== Creating a Virtual DNS Entry ==

If using the single channel authentication such as [[Single Channel How To Guide| TURing]], or SMS confirmed Images, or SMS on demand buttons, an external DNS entry is required that points to the same IP address as the Juniper SSL VPN.

Example:

Juniper SSL VPN	vpn.mycompany.com IP 1.1.1.1
Turing Image	turing.mycompany.com IP 1.1.1.1

Swivel Example:

Juniper SSL VPN	vpn1.swivelsecure.com IP 1.1.1.1
Turing Image turing.swivelsecure.com IP 1.1.1.1


=== Creating a role for Virtual hostname ===

Create a role for the Virtual hostname. Then under User Roles/<role name>/Web/Bookmarks, the role does not need any web bookmarks, but under the Options, advanced settings set ''Allow browsing untrusted SSL sites, and remove the option'' to ''Warn users about the certificate problems''.


[[Image:PINsafeJuniper7allowbrowsing.jpg]]


=== Creating an ACL for the Virtual hostname role ===

An ACL must be created on the Juniper SA to allow access to the Swivel server. For further information see [http://www.juniper.net/techpubs/software/ive/guides/howtos/How_To__PTP.pdf]

A new policy and role may be required for this. Select Resource Policies/Web Access Policies/<Policy Name>/General, under Resources enter the Swivel internal address:

Example https://pinsafe.swivel.local:8443/proxy/*

For Roles select Policy Applies to selected roles, add the required role to the selected roles.

For Actions select Allow Access.


[[Image:PINsafeJuniper7ACL.jpg]]


=== Creating the Virtual Hostname ===

To create a Virtual DNS entry, on the Juniper SA select the Authentication/Signing In/Sign-In Policies and then select New Page. Select the Authorization Only Access radio button for User type. Complete the following information:

'''Virtual Hostname:''' enter the DNS name that will point to the Swivel virtual or hardware appliance for the TURing image. 

Example:	turing.swivelsecure.com/

'''Backend URL:''' enter the protocol, IP address and port of the Swivel virtual or hardware appliance

Example for a Swivel virtual or hardware appliance: http://192.168.0.35:8443/*

For a software only install see [[Software Only Installation]]

'''Authorization Server:''' select No Authorization

'''Role Option:''' Select a Role

Save the Changes

[[Image:Virtual Hostname.jpg]]


=== Verifying the Virtual DNS Entry ===

Swivel virtual or hardware appliance

From within the network verify the Swivel server is working using the below to generate a TURing image

http://<PINsafe appliance URL>:8443/proxy/SCImage?username=test

Then verify the external access using

https://<turing.mycompany.com>/proxy/SCImage?username=test


Software Install

For a software only install see [[Software Only Installation]]

Then verify the external access using

https://<turing.mycompany.com>/pinsafe/SCImage?username=test


== Login Page Modifications for Single Channel Authentication and SMS On Demand ==

The sample pages provided by Juniper on the current version to be integrated, should always be used, as these are the supplied compatible pages and contain the latest updates and security features. To obtain these, login to the Juniper and select Signing-In, Sign-in pages, then click on Upload Custom Pages.


[[Image:Juniper upload custom pages.jpg]]


Click on the '''Sample''' and download the latest sample pages. This is a zip file, and any additional files or changes will need to be added back to the zip file with the original contents, to be uploaded again.


[[Image:Juniper sample.jpg]]


Using the sample login pages we can add the Swivel modified pages (see prerequisites), and change them to suit the integration requirements.

The configuration section within '''LoginPage.thtml''' should be edited to suit your environment as the below modifications.

If you are using the combined PC and tablet version, you should make these changes to swivel-header.thtml.

=== Modifying the Login Page ===

{|border=1
|+ OTC_OPTION Controls how the TURing image will be displayed to the user
|-
| Option || Description || Single channel Option || Dual Channel Option
|-
| image || When the user tabs down from the username field, the TURing will automatically show || Y || N
|-
| button || The login page will present a TURing button. Click the button to display the TURing || Y || Y
|-
| disable || No TURing image || Y || Y
|}


{|border=1
|+ OTC_RANDOM Displays a button on screen to refresh the TURing image
|-
| Option || Description || Single channel Option || Dual Channel Option
|-
| true || Button will be displayed || Y || Y
|-
| false || No button || Y || Y
|}


{|border=1
|+ TURingImage URL for generating a TURing image 
|-
| Option || Description || Single channel Option || Dual Channel Option
|-
| URL (see below) || Change the TURingImage value to reflect the IP address of the Swivel appliance || Y || Y
|}


The URL may be one of the following:


*Using Virtual DNS

Swivel appliance

  https://virtual_hostname/proxy/SCImage?username=";

Software install

  http://virtual_hostname/pinsafe/SCImage?username=";


*For a NAT or Public IP address

Swivel appliance

  https://hostname:8443/proxy/SCImage?username=";

For a software only install see [[Software Only Installation]]

=== Modifying the Welcome Message===

To customise login page welcome message, you must edit the LoginPage.thtml (and LoginPage-stdaln.thtml if using Network Connect):

Search and remove the following:

<% welcome FILTER verbatim %>

This references the first line of the Welcome message. E.g. change this to "Welcome to the"

Search and remove the following:

<% portal FILTER verbatim %>

This references the second line of the Welcome message. E.g. change this to "Swivel Secure Login Page"

=== Modifying the login for SMS Only requests ===

Swivel supports SMS on Demand, SMS in advance and SMS using Two Stage authentication. Where SMS on demand only, is used, the login page may be modified so that instead of generating a TURing image a SMS is sent to the user. Locate the following line:

https://virtual_hostname/proxy/SCImage?username=";

and modify the SCImage?username=" to DCMessage?username=;

Example:

*Using Virtual DNS

Swivel appliance

  https://virtual_hostname/proxy/DCMessage?username=";

Software install

  http://virtual_hostname/pinsafe/DCMessage?username=";


*For a NAT or Public IP address

Swivel appliance

  https://hostname:8443/proxy/DCMessage?username=";

For a software only install see [[Software Only Installation]]


=== Modifying the login button text ===

The login page button and link to ''Get Another Image'' may be modified.

To modify the login button text locate the text ''value='Turing''' and replace the Turing with the required text.

To modify the ''Get another image?'' URL, locate the two instances of ''Get another image?'' and change the text as required.


=== Modifying the login for PINpad ===

Customising for [[Pinpad]] can be done using the same custom pages as above. Follow the same instructions as above, except the following:

* The zip file contains 3 additional images that need to go into the ''imgs'' folder of the Juniper custom login.

* '''OTC_OPTION''' needs to be set to '''"pinpad"'''.

* You need to set the value for ''PinpadImage'', rather than ''TURingImage'' to match your own Swivel instance.

Example

  var PinpadImage = "https://hostname:8443/pinsafe/SCImage?username=";

to

  var PinpadImage = "https://hostname:8443/pinsafe/SCPinPad?username=";

=== Modifying the Login pages for Mobile Devices ===

The prerequisites section contains the mobile modified pages that can be uploaded with any other modified pages to ad wivel authentication to the login.

Modify the file PageHeader-mobile-webkit.thtml, find the below line and change the link for the Swivel appliance as the standard login page above.

var TURingImage = "https://pinsafe.company.com/proxy/SCImage?username=";


[[File:JuniperBlackberry.jpg]]


=== Juniper Network Connect login page modification ===

The Juniper Network Connect can be started directly, and to customise the login page for Swivel authentication copy the login.thtml page to LoginPage-stdaln.thtml


[[Image:Juniper Network Connect login.jpg]]


Juniper Network Connect with TURing


[[Image:Juniper Network Connect login TURing.jpg]]


=== Uploading the Modified Page ===

Ensure all the modified files are included with the zip file to upload to the Swivel server. On the Juniper select Signing In/Sign-in Pages then click on Upload Custom Pages.


[[Image:Juniper upload custom pages.jpg]]


Enter a Name for the Custom page, then use Browse to find the location of the Templates file. Then click on the Upload Custom Pages, observe any errors that may occur.


[[Image:Juniper custom sign in page.jpg]]


The new signing in page should be listed.


[[Image:Signing in page.jpg]]

= Verifying the Installation =

Navigate to the login page and verify that the page is as expected. Test a login using an OTC and verify the user can login with a correct OTC an fails with an incorrect OTC.

Dual Channel Authentication

[[Image:Juniper login.jpg]]


Single Channel Authentication

[[Image:Juniper login TURing.jpg]]


= Uninstalling the Swivel Integration =

To remove Swivel, remove the customised page, Swivel realm, and Swivel Policy.


= Troubleshooting =

Check the Swivel logs. If the Single Channel image is used then a 'session start' should be see for the username. RADIUS authentication requests should be seen for successful or failed login attempts.

Check the Juniper logs, look for user authentication requests.

If the TURing image is not visible, right click on the red cross and view the details of the image URL.

Copy and paste this URL into a separate web browser, observe any certificate errors.


[[Image:Juniper login with internal URL.JPG]]


'''Internal Certificate Authorities'''

If an internal certificate authority is used, then the Single Channel image may not be accessible externally unless the client has installed the certificate as a trusted root certificate. Using a valid public certificate will remove this requirement.


'''domain\username is used instead of username'''

On the Juniper when USER is used then the domain name may be added in the authentication request to the Swivel instance in the form domain\username. When USERNAME is used then just the username is sent to the Juniper. 


= Known Issues and Limitations =

'''"ExceededConcurrent.thtml" is not found in zip file.'''

Ensure that the file is present.

Make sure that the files are not located in a sub-directory within the zip folder

Select All of the files within the folder and then send to a zip folder

== iPhone, iPad iOS automatic TURing image generation issue ==

The Onblur method in Javascript does not work in iOS, so a TURing button would need to be created to request the image after the username has been entered.

  <a class="wide confirm buttonTxt" href="#" onclick="var frm = document.getElementById('frmLogin'); if (onFormSubmit()) { frm.submit(); }">Sign In</a>

A modified login page is available here: [https://kb.swivelsecure.com/wiki/images/e/ef/LoginPage-ipad.zip iPad modified login page]



== Authentication fails after upgrading Swivel ==

In Swivel 3.8, the domain name was automatically removed for RADIUS authentication. However, this prevents authentication in cases where the domain\ prefix is required.

Assuming PINsafe is not the primary authentication, this can be worked around by changing the value passed to Swivel by the Juniper as <USERNAME>, rather than <USER>. This is in the Juniper settings for secondary authentication: "Username is predefined as".

= Additional Information =

Custom sign-in pages for Pinpad can be found [https://kb.swivelsecure.com/wiki/images/2/27/Juniper7Pinpad.zip here].
