SUPPORT WIKI : SAML Integration with NetScaler

Citrix Secure Web Gateway, formerly NetScaler Secure Web Gateway

What is SAML ?

Security Assertion Markup Language (SAML) is an XML-based authentication mechanism that provides single sign-on capability and is defined by the OASIS Security Services Technical Committee

Why SAML ?

The SAML authentication mechanism provides an alternative approach for Authenticating a User belong to a company for one or more service hosted at service provider that hosts a number of applications for the company.

Consider a scenario in which a service provider (LargeProvider) hosts a number of applications for a customer (BigCompany). BigCompany has users that must seamlessly access these applications. In a traditional setup, LargeProvider would need to maintain a database of users of BigCompany.

This raises some concerns for each of the following stakeholders:

  • LargeProvider must ensure security of user data.
  • BigCompany must validate the users and keep the user data up-to-date, not just in its own database, but also in the user database maintained by LargeProvider. For example, a user removed from the BigCompany database must also be removed from the LargeProvider database.
  • A user has to log on individually to each of the hosted applications.


The concerns raised by traditional authentication mechanisms are resolved as follows:

  • LargeProvider does not have to maintain a database for BigCompany users. Freed from identity management, LargeProvider can concentrate on providing better services.
  • BigCompany does not bear the burden of making sure the LargeProvider user database is kept in sync with its own user database.
  • A user can log on once, to one application hosted on LargeProvider, and be automatically logged on to the other applications that are hosted there.

In addition, SAML supports

  • Cross-Domain Single Sign-On (SSO)
    • A user authenticates to one web site (domain) and then is able to access resources at some other web sites (domains)
    • In simple words user “Alice” is authenticated at DomainA.com and can access resources at both DomainA.com and DomainB.com
  • Federated Identity
  • Attribute based authorization

SAML Terminologies :

SAML SP / Relaying party : Requester Role

SAML IDP / Asserting party : Responder Role

Assertion : Requests and responses

Metadata : Configuration data

SAML Service Provider(SP) :

The SAML Service Provider (SP) is a SAML entity that is deployed by the service provider. When a user tries to access a protected application, the SP evaluates the client request. If the client is unauthenticated (does not have a valid NSC_TMAA or NSC_TMAS cookie), the SP redirects the request to the SAML Identity Provider (IdP).

The SP also validates SAML assertions that are received from the IdP.

SAML Identity Provider(IdP) :

The SAML IdP (Identity Provider) is a SAML entity that is deployed on the customer network. The IdP receives requests from the SAML SP and redirects users to a logon page, where they must enter their credentials. The IdP authenticates these credentials with the user directory (external authentication server, such as LDAP) and then generates a SAML assertion that is sent to the SP.

The SP validates the token, and the user is then granted access to the requested protected application.

SAML Assertion:

Assertion is a claim, statement, or declaration of fact made by the SAML authority. It’s the information collection by the SAML authority.

Types of Assertions :

Authentication – the user is authenticated by a particular means at a particular time

Authorization – the user was granted or denied access to a specified resource

Attributes -the user is associated with the supplied attributes

Metadata:

Metadata is the configuration data in SP and IDP to know how to communicate to each other which will be in XML standards

Required root Element:

<md:EntityDescriptor> </md:EntityDescriptor>

Required Role Element:

SP: <md:SPSSODescriptor> </md:SPSSODescriptor>

IDP: <md:IDPSSODescriptor> </md:IDPSSODescriptor>

SP: <md:SPSSODescriptor>

1. <md:KeyDescriptor>

2. <md:AssertionConsumerService>

3. <md:AttributeConsumingService>

4. <md:NameIDFormat>

Types of Services :

Assertion Consumer Service : Request URL

Single Logout Service: Logout URL

As Service Provider(SP):

Assertion Consumer path: /cgi/samlauth

Single Logout path: /cgi/tmlogout

As Identity Provider(IdP):

Assertion Consumer Service Path: /saml/login

Single Logout Service: /saml/login

SAML Bindings :

  1. HTTP Redirect Binding
  2. HTTP Post Binding
  3. HTTP Artifact Binding


Web SSO Profiles :

The Web Browser SSO profile supports a variety of options, based on whether the message flows are IdP-initiated or SP-initiated and and whether the IdP pushes SAML assertions to the SP or the SP pulls them from the IdP.

The push approach involves using either HTTP redirects or HTTP POST messages to deliver a SAML message.

The pull approach involves sending a artifact to the receiver, which then uses the artifact to dereference and obtain the related SAML message.

A combination of message flow and binding techniques gives rise to eight different combinations as listed below.

  1. SP Initiated with SAML(Request and Response) Binding as POST
  2. SP Initiated with SAML (Request and Response) Binding as Redirect
  3. SP Initiated with SAML Request as POST and SAML Response as Redirect
  4. SP Initiated with SAML Request as Redirect and SAML Response as POST
  5. IDP Initiated with SAML(Request and Response) Binding as POST
  6. IDP Initiated with SAML (Request and Response) Binding as Redirect
  7. IDP Initiated with SAML Request as POST and SAML Response as Redirect
  8. IDP Initiated with SAML Request as Redirect and SAML Response as POST


SP-Initiated SSO—Request and Response as POST (Refer 1 above) :

In this scenario a user attempts to access a protected resource directly on an SP Web site without being logged on. The user does not have an account on the SP site, but does have a federated account managed by a third-party IdP. The SP sends an authentication request to the IdP. Both the request and the returned SAML assertion are sent through the user’s browser via HTTP POST.

Processing Steps :

1. The user requests access to a protected SP resource. The request is redirected to the federation server to handle authentication.

2. The federation server sends an HTML form back to the browser with a SAML request for authentication from the IdP. The HTML form is automatically posted to the IdP’s SSO service.

3. If the user is not already logged on to the IdP site or if re-authentication is required, the IdP asks for credentials (e.g., ID and password) and the user logs on.

4. The IdP’s SSO service returns an HTML form to the browser with a SAML response containing the authentication assertion and any additional attributes. The browser automatically posts the HTML form back to the SP.

5. If the signature and assertion are valid, the SP establishes a session for the user and redirects the browser to the target resource.

SP-Initiated SSO—request as Redirect- Response as POST (Refer 4 above) :

In this scenario, the SP sends an HTTP redirect message to the IdP containing an authentication request. The IdP returns a SAML response with an assertion to the SP via HTTP POST.

Processing Steps :

1. A user requests access to a protected SP resource. The user is not logged on to the site. The request is redirected to the federation server to handle authentication.

2. The SP returns an HTTP redirect (code 302 or 303) containing a SAML request for authentication through the user’s browser to the IdP’s SSO service

3. If the user is not already logged on to the IdP site or if re-authentication is required, the IdP asks for credentials (e.g., ID and password) and the user logs on.

4. Additional information about the user Attributes may be retrieved from the user data store for inclusion in the SAML response.

5. The IdP’s SSO service returns an HTML form to the browser with a SAML response containing the authentication assertion and any additional attributes. The browser automatically posts the HTML form back to the SP.

6. If the signature and assertion are valid, the SP establishes a session for the user and redirects the browser to the target resource.

IDP-Initiated SSO—Request and response as POST (refer 5 above) :

In this scenario, a user is logged on to the IdP and attempts to access a resource on a remote SP server. The SAML assertion is transported to the SP via HTTP POST.


Processing Steps :

1. A user has logged on to the IdP.

2. The user requests access to a protected SP resource. The user is not logged on to the SP site.

3. Optionally, the IdP retrieves attributes from the user data store.

4. The IdP’s SSO service returns an HTML form to the browser with a SAML response containing the authentication assertion and any additional attributes. The browser automatically posts the HTML form back to the SP.

5. If the signature and assertion are valid, the SP establishes a session for the user and redirects the browser to the target resource.

Netscaler Deployment :

The NetScaler appliance can be deployed as a SAML Service Provider (SP) and a SAML Identity Provider (IdP).

When the NetScaler appliance is configured as an SP, all user requests are received by a traffic management virtual server (load balancing or content switching) that is associated with the relevant SAML action.

When the NetScaler appliance is configured as an IdP, all requests are received by an authentication virtual server that is associated with the relevant SAML IdP profile.

Note :

  • A NetScaler appliance can be used as a SAML SP in a deployment where the SAML IdP is configured either on the appliance or on any external SAML IdP.
  • A NetScaler appliance can be used as a IdP in a deployment where the SAML SP is configured either on the appliance or on any external SAML SP.

Refer the Docs page below for detailed steps on configuring NetScaler as a SAML IdP or SP.

Packet capture :

Req 1 to the LB VIP :

Netscaler will reset the cookies and in the form action we see the redirect URL as IDP URL with SAML Request

Req 2 to AAA VIP:

Once the SAML request is validated against the parameters it will redirect to /tmindex.html if it is configured on AAA VIP.

Req 3 to SP LB VIP:

User post the SAML response after user is validated against LDAP. After the validation of assertion, it will redirect back to the original request received to LB along with the Set-Cookie Value which set during the authentication
