10.4 10.5 10.6 10.7 10.8 server all allow multiple user login
Did you use PM or wgm or server app to configure users
How does your working user compare to the none working user
Check your user groups or computer groups are not preventing the user account from being created on the client machine
Check server logs they may show why the account "can't be logged in"
ML 10.8 server
PM was used to configure users
all 5 network users are working in that they can login to a computer
but no two users can login at the same time on the same computer simultaneously, ie, no fast user switching
have a look here reports of ML 10.8.2 fixing this problem
I think that's a different problem?
My problem is that from client machines fast user switching doesn't work period. Once one network user is logged in, no one else can login on that computer unless that first user logs out. Very annoying b/c it means that staff can't share computers during the day without logging out, which costs precious time.
I do not belive you can fast user switching for network users for the reason indicated here : https://discussions.apple.com/thread/2502677 Despite referring to the older OS version the AFP issue is the same.
This one makes the same point. http://forums.macrumors.com/showthread.php?t=1048613
I have tried this with each major update and found the same result you did. It seems to be a limitation of AFP.
I believe you can use it for local users which exist on the client machine.
