Thanks, for answering. I understand how it works with ADS evaluation. But that's rather strange.
First of all, PHP Connector was always free to download in all versions and it is only needed if someone has ADS/AIC Server. And it only works with the latest version (connector should not be newer than the server it connects to). And unlike ODBC and OLE DB drivers it doesn't work locally (server is needed anyway). So, there is no way someone would misuse it.
Secondly, we have Windows ADS Server, but we need Linux PHP Client. So, there is a chance that we would purchase a costly server, but still would be unable to download Linux PHP Connector, as it's a part of Linux package.
Thirdly, I've got a working version of 9.1, installing later versions of ADS PHP Connector were unsuccessful (we tried 3 times, with different external specialists). So, I assume, that there is a very high probability that 12th version would also have problems. Purchasing of a new version would be very risky. So, I doubt, that we would make this move.
So, please, consider including ADS PHP Connector to evaluation package as well. Or make a temporary exclusion for testing purposes.
