When using a older Access Server SDK (7.0.4) with a newer Access Server (10.1.4) running in backward compatibility mode recently, the Access Server SDK always returned cookies that were logged out. The reason turned out to be because the time was never set on the machine the SDK was installed on.

However, the Access Server SDK installed correctly when it was installed. In previous incarnations the Access Server SDK would have never been able to be configured properly if a significant time difference existed.

This definitely falls squarely in the realm of user error, as the documentation clearly stipulates that when cert or simple mode are used the times have to be synchronized between client and server. In previous releases though you would never have been able to complete the SDK configuration. I can only imagine this has something to do with "backward compatibility" mode.
