I am setting up a single workstation (kiosk) in my local library for a team of genealogy researchers (approx 12-14). I plan to use Ubuntu 12.04 LTS as the OS.

1. Each user must have a unique user ID and password


2. Ideally, I would like each user to enter their user ID manually. By default LightDM allows the user to select their name from a scrolling list. (this is not a showstopper though)


3. All users must to access a single desktop environment and the same home directory for document collaboration (single document repository for all users). I also want to avoid configuring the desktop UI look and feel as many times as the number of users.** I have planned a branded desktop background, launcher layout and other things consistent with a Training manual I am putting together.


4. I need to audit log in logout date/time stamps for each user to capture time spent. The answer to this question helps me with this point. (I will need to understand if the answer is still valid as it was written in 2010.)

I am asking a very specify question; Is what I have described above holistaically achievable and if so how? I will accept a "No" or "Probably not" answer. If that is the case please help me understand with a brief "why" and I will go back to the drawing board. The reason for asking the question is that I suspect its not achievable but want to be 100% sure.
