    IIS and CALs - getting lost in this

    Guys, running IIS with a web portal on 2008R2, do I need a CAL for every connecting client?

    Is there any rule of thumb to remember?

    you shouldn't need cals for AD auth either is my estimation. Basically because your application will only be making the connection to AD itself, rather than each user.

    Seriously the best thing to do is to contact a microsoft representative.
    Microsoft licensing is a study on it's own..
    This looks interesting: http://forums.iis.net/t/1149662.aspx

    For the web side, no CALS (according to http://www.microsoft.com/windowsserv...s/pricing.aspx).

    Not sure about SQL server, but I was told in the past that if the APP is accessing the dB that counts as one user (else large scale sites with 000's of connections would be killed with licensing )

    Thanks, so AD auth might be a problem, and SQLexpress/mysql need an additional investigation

    the simple answer, as far as I'm aware, is for a web application, no you do not need CALs

    if you're connecting to SQL, as dumber pointed out, you will need a connection license - however, if you only have one web server connecting to one SQL server, then your app may only have one connection...

    This can give you a start...

    I also believe you need to pay if you want to use AD authentication however I don't know a lot about licensing.. Contacting MS is the way to go I think.

    Then the licensing rules for those products would apply instead of the not-free editions of SQL Server.

    What was your source for that info? Keep in mind that you can limit the number of concurrent connections to IIS to match the number of CALs you have, however I would be inclined to agree that it sounds a little dubious.

    As an aside... is IIS considered core to the OS? If so, it would follow that you would need a CAL to use it, while you wouldn't need one to connect to Apache running on Windows Server.

    So I'm hoping there is someone around here who has been through this stage in life (and I'm not ready to move to apache on absolutely every server... yet)

    If your web app uses SQL Server, then you do need an SQL CAL for each connection. However, according to the VL consultant we hired when we got our VL in place, we didn't need CALs for connections to IIS.

    However, I would strongly recommend that your best answer is going to come from phoning the Microsoft licensing number. It'll cost you a few quid, but it'll be significantly cheaper than asking a consultant the same question. And then you'll be hearing it straight from the horse's ars... mouth.

    I must stress however that our IIS platform was running on Windows Server Standard; I have no idea if the same rule apples to Windows Web Server, or if you would require CALs for that.
