Thanks for your excellent guide. I have been staggering with exactly the same problems for some time now. First had everything on AFP/SMB. Noticed that it won't play with fast user switching. Then switched to NFS, but noticed that files were modified with user/group permissions. So went back to AFP: but I hate it
. So going for NFS again.
Can you confirm that with aligning the user / group id's between MAC and DS, it is possible to open itunes library from different user accounts.
Right now if I open library on NFS, the permission change to only read/write to 501. So when user 502 tries to open it.. doesn't work. Even when not in use by 501.
