Do I require both a Runtime and SQL User CAL for each user?

Clarifications

If you ring the M$ Licensing Center you are most likely to get different answers from different people you speak to and most defiantly different answers depending on how you phrase the question.

If you rely on the M$ Licensing Staff they will very likely mislead you and place you in a position where M$ Accuses the Company of Piracy. This happens because the people who work at the M$ Licensing Hot Line are only trained to read a screen and not fully understand the actual License Agreement.

As this is a Legal Document you should speak to the M$ Legal Department every time you have a Licensing Question and get their Answer in writing. That way if they decide that you are doing something wrong you have a comeback and while you will be required to buy the Additional CAL's/Licenses they will not instigate a Full Scale Legal Session against the company.

From past experience I now always ask the Head of the M$ Legal Department here for their opinion and follow their answers to the letter. May be slightly more expensive initially but it certainly stops any problems latter. ;)

However you need to speak to your Local M$ Legal Department because Local Laws differ around the Globe and within different areas of the same country.

SQL 2005 has a couple different types of licensing.

Processor license, Server plus device, server plus user.

If you read on MS site, it gives you the different licensing options and what they mean.
