I have a client who recently purchased SQL 2014 Enterprise Edition with 5 CAL licenses. The installation was done remotely. Question is how does one go about verifying that there are indeed 5 CAL licenses that are present?
You can't verify this. There is no method. The licensing deal is between the client and Microsoft.
There are indirect methods, say if they have a public web site then CALs are useless and they should have core licences. How to to plan to enforce such a thing on behalf of Microsoft anyway?
