When you are using Citrix FAS you will also have a Authorization Certificate. Without this certificate Citrix FAS would not be able to function. The same is applicable when the Authorization Certificate is expired, FAS can no longer do it’s job. When the Authorization Certificate is expired users are no longer able to login. Because FAS cannot request new smartcard certificates for a user.

HowTo - Windows - Export certificate (pfx)

group: “Windows”

Certificates are an important part of a modern environment. They make communication safer by encrypting the traffic between the client and server. A safe way to move certificates between servers or store them safely is by exporting the certificate (private and public key) to an encrypted format. A commonly used format is “pfx” (Personal Information Exchange also known as PKCS#12). A pfx file can contain one or more certificates and is encrypted with a password. Without the correct password the pfx is useless. You commonly see that a pfx contains a (web) server certificate and one or more intermediate certificate(s) and a root certificate.

Edit 07-04-2017: Check out my new and updated version! I’m trying to create an (PowerShell) script to automate the Let’s Encrypt certificate creation. Specifically for the Citrix NetScaler. Currently still Work In Progress… It’s not yet finished. The prerequisite is that you have a configured NetScaler (http) Content Switch vServer. The script will present you with the required configuration rules (it will also be copied to your clipboard so you only have to copy it in the cli of the NetScaler) For the meantime you can find it on GitHub: GenCertForNS on GitHub More soon (I hope)…
