I have 25 systems of ubuntu and I want to create 60 login id and password for students. And any students can use any system to use system using his/her credentials. How can I achieve this?

I run a small academic research group and we have 4 workstations and one server, all running Ubuntu. I would like to have login credentials that are shared across all workstations and the server, so I can issue a userid once, and the user could sit down at any workstation and login. Nominally, the filesystem would be shared so that the user could have their files/desktop environment at any workstation. Is there any way to set up such a environment?

This afternoon I set up a Win Server 2008 R2 system for use with Team Foundation source code control. In order to give my team-mates the right to connect, I had to create a user account for each person, 10 in total. (I can't, and I don't want to create a domain).  Now, after doing this, all user accounts are displayed in the login screen.  What can I do so that all the accounts are not displayed there?

Suppose you want to generate a password using ASCII  characters ($128$ characters.)How many ways can you create a password of 10 characters long that has at least one lowercase letter (a-z) and at least one number ($0-9$)?  ** MY ANSWER: $26*10*(128)^{10}$**  I don't understand why this is wrong? Can anybody help? Thanks!

Quick question: I have a situation where I need to let multiple people on different PCs log into one server 2008 machine as administrator simultaneously over remote desktop. I have the CALs for it, it's just not set up correctly. When one user tries to log in, it boots the other out. What I need is to present to them a different session, just each as logged in as admin. Sorry for the slightly rambling post, I'm new here. Thanks!

I'd like to join three ideas into one interesting and sometimes useful feature. There was a question about using multiple passwords earlier this year, but it didn't receive much attention. I'd like to ask the question again after showing an interesting and new way to use the feature. The three original posts I found to be interestingly combined were:        Basically I'd like to login to my account with two passwords and depending on the password I use, I would get a different content in my home directory. In a way I would get a cryptographically hidden account into my system. So the question is, is it possible to allow multiple passwords to log on to Ubuntu/Linux for the same user?

On a site with premium user account subscriptions, I'd like to be able to limit logins to one computer at a time. The most straightforward way to accomplish this would be to limit by IP, but I haven't had any luck finding a plugin to accomplish this. Does anybody know of one I can use to get this functionality?

I just put Ubuntu 15.04 on a flash drive using pendrivelinux, and when attempting to install it on my computer, it asks for a username and password.  What is the default username and password?  I haven't been able to find it anywhere on the web.  Thanks!

I got a brand new Windows 7 machine, installed the operating system, created one account and forgot its password. What can I do?  There is no external CD, the operating system is loaded from somewhere inside the machine.  I already tried to remember passwords and tried all candidates with all possible combinations of caps lock, num lock etc.

I was browsing through some Linux questions and saw this interesting question.   What steps to add a user to a system without using useradd/adduser?  The one possible way that comes to my mind is,   Add an entry for the user in /etc/passwd file.  Add an entry for the group in /etc/group file.  Create the home directory for the added user. Set the new user password using the passwd command.    I tested the above approach and it worked fine.   Is this the only possible way or is there any other work around to achieve this?

When I attempt to perform certain actions within ubuntu I am asked to authenticate with a root user, but ubuntu doesn't give me options for which root user, it just specifies it as the user that set up my machine. I was wondering how to go about changing which user it selects to run the authentication?  For instance, if I want to install software from the Ubuntu Software Center I am asked to authenticate with user X and I would like to change that to be user Y globally.  I am also aware that I can just run things with sudo from the command line, but I don't want to have to do that.  I'm using ubuntu 14.04. And user Y is in the sudoers file and as of now user X is not.

Here are my circumstances:   I am running Ubuntu 12.04. I have one user account.   I absolutely hate the password requirement. How do I disable this requirement such that my Linux computer will behave more like Windows in this respect? I do not want to hear that I shouldn't this because it is not secure. This is my desire so the concern of security is effectively null and void.

I'm working on a Ubuntu system, and my client has completely forgotten his administrative password. He doesn't even remember entering one; however it is there.  I've tried the suggestions on the website, and I have been unsuccessful in deleting the password so that I can download applets required for running some files. Is there a solution?

It's easy to have multiple user accounts on one computer and even switch between accounts without logging off. It is also possible to have more than one display connected to a single computer.  Is it possible to have one multi-core computer be used simultaneously by two users in their own accounts? Is there specific hardware required (to allow keyboard and mouse distinction for each user) and software configuration?  I know you can setup remote connections on windows that allow you to open and use a second user account without bothering the first user, but how about working locally on the same machine, essentially removing the network delay of remote desktops?  What OS supports this? Linux Ubuntu? Windows 7?

When a user boots Windows is there a way to only show a single user that then asks for a password. For example, I have an admin user and a regular user. When the computer boots I do not want the user to see the admin account. Is this possible? If so, how would an admin then login?  I have Windows 7 if that matters.

I want to have more than one user logged on at the same time, on the same computer. Each user should have a full X session. It is easy enough to log in to multiple concurrent non-X Linux terminals, but I want the X factor. Maybe I've missed something, but I only see a Main Menu option to Log out of the current user, and nothing for Switch User. Is there a simple way to do this?

After I read  I noticed that there is a user account named 'nobody' in my Ubuntu system.   Also I noticed that I can login in this account from terminal using the following command and my password:  sudo su nobody     It doesn't mind me at all, but I want to know what is the purpose of this user? Is it created by default on a fresh install of Ubuntu or is created by installing a particular package?
