How to download PAM Client installer files?
The default CA Distribution Network url is https://d21oi5tjuccwe.cloudfront.net/. When you go to this url you will see something like the following:

Find the Key entry for the version you want to use. You can see a couple highlighted above. Take this string and add it to the first url. For 2.8.0 this would be https://d21oi5tjuccwe.cloudfront.net/ca-pam/install/linux64/CAPAMClientInstall_V2.8.0.bin. Use this url to download the 2.8.0 installer.
Please note that there will not be a new installer version for every version of PAM, and the client, that is released. For example, there is no 2.8.1 or 2.8.2 installer. The 2.8.0 installer will be used.
