Citrix ADC (SAML)

Cloudflare Zero Trust can integrate with Citrix ADC (formerly Citrix NetScaler ADC) as a SAML IdP. Documentation from Citrix shows you how to configure Citrix ADC as a SAML IdP. These steps are specific to Cloudflare Zero Trust.

​​ Set up Citrix ADC (SAML)

To set up Citrix ADC (SAML) as your identity provider:

  1. First, you’ll need to configure 2 SAML certificates:

    • A certificate to terminate TLS at the vServer. Ensure that the certificate is issued by a publicly trusted CA.
    • A certificate for signing SAML assertions.

    If you do not already have a certificate for signing SAML assertions, you can use a self-signed certificate generated on Citrix ADC by following these steps:

    1. Go to Traffic Management > SSL.
    2. Select Create and Install a Server Test Certificate.
  2. Select Configuration and enter a Certificate File Name, Fully Qualified Domain Name, and a select a Country.

    Citrix AD Create and Install Test Certificate interface with file name, domain name, and country
  3. Create a publicly accessible authentication vServer and configure the user identity source (like, local users, LDAP) by following this Citrix documentation.

    For the rest of this example, the user refers to the IdP address

​​ Add a new profile

  1. Go to Security > AAA - Application Traffic > Policies > Authentication > Advanced Policies > SAML IDP to add a new profile.

    Include the following required configuration details:

    NameThe certificate name you defined while configuring SAML
    Assertion Consumer Service URLhttps://<your-team-name>
    IdP Certificate NameThe IdP certificate name you defined while configuring SAML
    Issuer Namehttps://idp.<yourdomain>.com/saml/login
    Service Provider IDhttps://idp.<yourdomain>.com/saml/login
    Name ID FormatEmailAddress
    Attribute 1email = AAA.USER.ATTRIBUTE("email")

    Cloudflare Access currently sends the IdP address in place of the Service Provider ID for the AuthN request.

  2. Create an Authentication Policy that refers to the Profile just created, and bind it to the authentication vServer mentioned above.

    Citrix AD Configure Authentication SAML IDP Policy

    To configure all of the above using just the CLI, run the following:

    add authentication samlIdPProfile samlProf_CloudflareAccess \
    -samlIdPCertName SAML_Signing \
    -assertionConsumerServiceURL "https://<your-team-name>" \
    -samlIssuerName "" \
    -rejectUnsignedRequests OFF \
    -NameIDFormat emailAddress \
    -Attribute1 email \
    -Attribute1Expr "AAA.USER.ATTRIBUTE(\"email\")" \
    -Attribute1Format Basic \
    -serviceProviderID ""
    add authentication samlIdPPolicy samlPol_CloudflareAccess -rule true -action samlProf_CloudflareAccess
    bind authentication vserver nsidp -policy samlPol_CloudflareAccess
  3. In Zero Trust, go to Settings > Authentication.

  4. Under Login methods, select Add new.

  5. Configure the fields as follows:

    NameYour chosen name
    Single Sign On URLThe FQDN of the IdP, with the path /saml/login
    IdP Entity ID/Issuer URLAs above
    Signing CertificateThe public certificate from the NetScaler
    Email attribute nameThis is listed under Optional configurations
  6. Select Save.

To test that your connection is working, go to Authentication > Login methods and select Test next to the login method you want to test.
