Does anyone know if the PAM 3.1.1 thick client has an unattended installation option?
You can do a silent install, but we don't have any official specifications for an "unattended" installation. You may be able to use the silent installer in combination with some kind of deployment tool to deploy in a more "unattended" way.
Documentation on Silent Install for CA PAM Client:
