Software Licensing per user, device CAL's, and other softwar

hi

i have just started to use the 30 day trial version of SD, i am very happy with it and will purchase the license when the new version comes out.

all is working well but i have a question with regards to licensing

i have just purchased software assurance licensing from Microsoft, i have added a PO and added each software license item and have submitted the po, and received the goods, these licenses have now been added to the asset inventory

i have scanned my workstations but am wondering how i can allocated these purchased licenses to the assets. when i add software licenses via the workstation inventory it seems to add more asset items,

also the scan does not seem to differentiate between server and advanced server, and or exchange standard or exchange enterprise version.

finally how do i allocate user licenses to users and not to devices, many of our users have multiple devices and i have opted for per user licensing (office, user cals etc) but i cannot see a way to allocate licenses to users.

i hope the above is clear but please do contact me if i need to elaborate on the licensing issues

many thanks
