I was a bit unsure how to phrase the title to this question so apologies for any confusion.
This is a lab environment (higher ed) with ~300 machines. We are upgrading our image to Windows 10 this summer but we need to address login and user-profile creation. What we want to do is authenticate users (using AD), but not use roaming profiles or have to wait for profile creation every time they log in. Keeping individual profiles on the machine is not an option. With our GPOs and other issues, logging into a domain account that needs created can take 2-5 minutes. We need students to be able to hit a desktop in under 30 seconds.
In the past we have used pGina to alter the login account once a user is authenticated. We maintain 2 local machine profiles (one for students, one for the public) and after authentication occurs we shunt the user into the proper local profile. This has worked pretty well for the past couple years. We get authentication, we get logging/auditing from the DC, no buildup of profiles, and fast login. However, pGina development has slowed or halted and currently does not work in Windows 10 with not word on when or if it will.
We are open to all suggestions - even commercial software if such exists. I cannot seem to find anyone else who has met this challenge, although it is inherently difficult to search for as all the related keywords bring up vastly different scenarios and problems.
Now I know what we really need is VDI or some virtualization tech most likely, but that requires more cooperation from the overall IT organization than we are likely to get in time to roll out a new image over the summer. So although I am open to all suggestions, even commercial ones, we are pretty limited to the environment and ecosystem we already have.
