Set up the Citrix registration authority
To complete the Citrix FAS integration, you need to get and install the certificate for the Citrix registration authority (RA) and configure the rules for issuing user certificates.
Aviso
DigiCert uses the "offline" method to get the long-lived RA certificate. You will request the certificate out-of-band through the Trust Lifecycle Manager REST API and then use a Citrix cmdlet to import the certificate into Citrix FAS. For additional details from Citrix, see https://docs.citrix.com/en-us/federated-authentication-service/current-release/config-manage/private-key-protection.
a. Generate the CSR in PowerShell
Enter the following two Citrix cmdlets in Windows PowerShell to generate the CSR for the RA certificate:
> Add-PSSnapin Citrix.Authentication.FederatedAuthenticationService.V1 > New-FasAuthorizationCertificateRequest -address <FAS server host>
For example:
PS C:\Users\Administrator> Add-PSSnapin Citrix.Authentication.FederatedAuthenticationService.V1 PS C:\Users\Administrator> New-FasAuthorizationCertificateRequest -address localhost Id : 497cd087-0970-4dbd-81f7-bbdc6b96961a Address : [Offline CSR] TrustArea : CertificateRequest : -----BEGIN CERTIFICATE----- MIICaDCCAVACAQIwIzEhMB8GCgmSJomT8ixkARkWEUNpdHJpeFRydXN0RmFicmljMIIBIjANBgkq hkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAwmkT9l4IKI9icLgmrSKiwMCRkN5CnIj57zZI6v4IC7qC 1hyItEbcFdfKn9oQ9v2ykb33oooD288onx61ujNadeIGb7YCq5lz+ZfROVXrzuPzC6dtQOlF4YwX mqkujv16aVl0w8mTZtV78YfykaHT4xmilyAT5GnDwcteOXGcduEzPhtnyOgdRlFbf5LudF35e+it ixHz3ZD3p5n9HXsgF65zs/GXiVkU7Pggt8Nw+6IZYPqs8ZnWtI28F48v3uY3zZ4TnZtx28XYgoLa ZTdJQbSirJsKI2B0lQHK7sZv+XnFHZtgXx3qCO64Wxz0vJgU4z0teATRShQ09CJEWKka3QIDAQAB oAAwDQYJKoZIhvcNAQENBQADggEBAHsJjJyZqKVx12uGnjuMSgbqXSaMUFqPc5Mse+NgdPcKa4EJ F17iYuEQpUTbtQDCGe7C8ndIfTitXIplGrDmrJZS5+oUTNGPwC15/J2aV1iBBN2AJeHm4VjtS8GH hErUW+RZRnZmVLNjEnH0cQqFDwgTvTR0fqc7hmwwhu1RRUJWYKCYR6ycjjNDFh6YHYAIhFvm7ogN aMpUzx2a1SbbcQq/cA6noUj9r54bf+FxZpbsY1/yj/Q8P8QAY0+/IPsq8SI1Ks4e2Hcp2c47FbVO E/nzNgob5vdPU4fT9DKDSv1F4hk47KK+uYh73NxZ1UaYioZH3Jf4gden+rFeORTIqg0= -----END CERTIFICATE----- Status : WaitingForApproval
Copy the contents of the Id
and CertificateRequest
fields from the response and store them somewhere safe. You will need them to request the RA certificate and import it into Citrix FAS.
b. Create the RA requester entity in Microsoft AD
You can use any type of Microsoft Active Directory (AD) entity to request the RA certificate, such as a User, Computer, or Service Account. For security reasons, DigiCert recommends using an entity that is only scoped to manage the Citrix RA certificate.
Make sure the userPrincipalName (UPN) of the entity is filled out. For Computer or Service Accounts, use ADSI Edit to add the UPN value.
The following example shows the use of ADSI Edit to add a UPN to a Microsoft gMSA service account:
c. Request the RA certificate via the Trust Lifecycle Manager REST API
To get the RA certificate, use the certificate
endpoint from the Trust Lifecycle Manager REST API's Inventory controller. You can read the API documentation by selecting Resources > API reference from the Trust Lifecycle Manager main menu.
Send the following values in the JSON request body:
profile
: The ID of the Citrix_RegistrationAuthority profile. You can get this from the profile details screen in Trust Lifecycle Manager.seat.seat_id
: Supply any type of identification string, such as an email address.csr
: Send the value of theCertificateRequest
field returned by the CitrixNew-FasAuthorizationCertificateRequest
cmdlet when generating the CSR. Remove the header, footer, and line feeds. Send only the raw Base64-encoded data.delivery_format
: Specify asPKCS7
.attributes.extensions.san.user_principal_names
: Supply the userPrincipalName (UPN) of the RA requester you created in Microsoft Active Directory.attributes.subject.common_name
: Same as above. Supply the userPrincipalName (UPN) of the RA requester you created in Microsoft Active Directory.
Below is an example Trust Lifecycle Manager REST API request and response for issuing the Citrix RA certificate:
To use the returned Citrix RA certificate, copy the value of the certificate
field in the response into a file. Remove the quotes and replace the line feed characters ("\n") with actual line feeds in the file, so it looks like this:

At this point, the RA certificate is stored in PEM format. You need to convert it to DER format before importing into Citrix FAS.
The following example shows how to use the openssl
command-line tool to convert a PEM certificate file called ra_cert.p7 into DER format and output to a new file called ra_cert_final.p7b:
openssl pkcs7 -in ra_cert.p7 -out ra_cert_final.p7b -outform der
Store the RA certificate file in DER format on the Citrix FAS system. You will import it into Citrix FAS in the next step.
Enter the following Citrix cmdlet in Windows PowerShell to import the RA certificate file in DER (p7b) format into Citrix FAS:
Import-FasAuthorizationCertificateResponse -address <FAS server host> -Id <Id from CSR generate> -Pkcs7CertificateFile <path to p7b file>
Make sure the Id
value you enter matches the one from the initial CSR generation. For example:
PS C:\Users\Administrator\Desktop> Import-FasAuthorizationCertificateResponse -address localhost -Id 497cd087-0970-4dbd-81f7-bbdc6b96961a -Pkcs7CertificateFile .\ra_cert_final.p7b Id : 497cd087-0970-4dbd-81f7-bbdc6b96961a Address : [Offline CSR] TrustArea : e28442fe-0bb8-435a-8ae5-ba96e5565bf5 CertificateRequest : Status : Ok
After importing the RA certificate, select Refresh on the top-right of the Citrix FAS console. It should now show a green checkmark for Authorize this service.
Configure the rules for how Citrix FAS authenticates users, as described in the Citrix documentation.
Under Template, make sure to select the Citrix_SmartcardLogon
certificate template:
Under Certificate authority, make sure to select your DigiCert Autoenrollment Server (AES) CA:
