Need to confirm if my customer can mix both type of cal on a same server farm.Microsoft answer not enough clear for my customer.What if some users need enterprise features and others do not? Once the Enterprise features of Microsoft Office SharePoint Server 2007 are enabled, every client accessing Enterprise functionality on that server, or servers in a farm, is required to have an Enterprise CAL in addition to their Standard Client Access Licenses.

that is correct. If you have enterprise loaded in the farm every user needs to have an enterprise cal

Microsoft sometimes allow a (presumably large) company to have a certain number of Standard+Enterprise CALs and a certain number of Standard only CALs provided the customer can prove that it is impossible (i.e. they have made technical measures to block this) for the set of Standard CAL customers to access *any* Enterprise functionality. This is not going to be worth doing for small companies who should just pay for Standard+Enterprise CALs for all users but for customers with users over maybe 50,000 in number it might be worth making the effort. It's said that some Microsoft offices have a more "flexible" approach to this (i.e. the level of proof that Std customers can't access Ent functions demanded by the offices varies from office to office and country to country). In the UK it is supposed to be virtually impossible to get permission for "mixed" CALs. In some other places it is supposed to be easier.FAQ sites: (SP 2010) http://wssv4faq.mindsharp.com; (v3) http://wssv3faq.mindsharp.com and (WSS 2.0) http://wssv2faq.mindsharp.com Complete Book Lists (incl. foreign language) on each site.

Hi, Please note that the ENT CAL is an “add on” to the STD base CAL. Therefore, users needing ENT functionality will need to have both the STD base CAL + the ENT CAL. I agree with Mike. As far as I know, there can be either standard licensing or the enterprise licensing on the same SharePoint server. You cannot have the mix and match of both. As far as the feature differences in various SharePoint products are concerned. For more information about SharePoint licensing, please refer to the following article: http://office.microsoft.com/en-us/sharepointserver/HA101655351033.aspx Thanks! Rock WangRock Wang MSFT

Hi, Im in the same situation - Need a mix of Enterprise and Standard users and thereformix of CALs. Number of users about 1000. As I see it - ONE solution to mix-problem is multi-tenancy and enabeling Enterprise feature packs for where it is needed only. For this I believe one also need/should have groups set up in Active Directory (create your EnterpriseUser group) which will be the only possible users to add to to a site with Enterprise features enabled. That way not even a unknowing Site administrator can mistakenly add users that lack Enterprise CAL to such a site. http://www.harbar.net/archive/2010/09/14/sp2010mt6.aspx In fact maybe multi-tenancy is not even needed ? Not sure. One could do this on any farm. Any one that can confirm that? I do agree that if Enterprise features are enabled on the farm then every new site from then on will be able to enable it and thus require double CALS for users. Since a mix of CALS then will be a nightmare to administrate in a Delegated security situation I would never do it - unless 50.000 user demand it :O) Just realized original question was for P2007 not SP2010. Multi tenancy is SP2010 feature
