Active Directory
UNH uses active directory for login purposes for faculty and students alike. Credentials are setup for all users when they join the college also known as your Blackboard ID and password. Even though designed for Windows it can be used on Linux based systems with LDAP or Kerberos.

Current status
We currently do not use Active Directory, instead choosing to create student wildcat accounts on caesar and all batch machines. We use ssh-keygen to create a authorized_key on a shared NFS mounted home directory that gives seamless access (i.e. ability to ssh to batch machines without need for passwords).

What was done prior to 2013?
Classes prior to the Spring 2013 class had attempted to add support for this for authenticating users when logging in to Caesar. From current understanding issues had arisen and it was moved to the back burner for things to be done on the project.

Create Domain Account
With joining the domain student accounts have a limit set to them of how many computers they can add to the domain.

The current limit (March 2013) is that a student can join 10 computers before getting blocked.

The best way to not increase a student's limit is to follow the instructions below. If not concerned skip ahead.

To begin setup of active directory it is best to setup the computer on the domain first
 * 1) *One will need access to the domain to add this either with IT Dept help or Tech Consultant with capable access
 * 2) Locate the CompTech OU (organization unit).
 * 3) Right click on the OU and go to New > Computer.
 * 4) Dialog box will open asking for computer name
 * 5) *Add computer name as: CAESAR (in all caps)

Now that the computer account is on the domain we can begin the process of joining.

How to Begin Active Directory Setup (OpenSUSE 11.3)
It is advisable to do the following steps and configurations will using the root account.
 * 1) Open the Menu at the bottom and open up YaST.
 * 2) Navigate through the YaST menu till you find the Windows Domain Membership Link.
 * 3) A dialog box should open saying that is connected to WORKGROUP and it will begin checking relations.
 * 4) *Do not cancel the check it may take up to 2 minutes.
 * 5) To add the computer to the domain change WORKGROUP to wildcat.unh.edu
 * 6) All options below textbox want to checked off except Use Single sign-on for SSH
 * 7) Make sure NTP settings are properly set or login will not work.
 * 8) Click OK at the bottom and it should prompt for Administrator password.
 * 9) *Change user name from Administrator to your Blackboard userID
 * 10) *Type in your Blackboard password
 * 11) *IF you have the proper credentials you should receive a message saying Welcome.

To test login using active directory, when looking at the list of users to select to login do the following:
 * 1) Select other user
 * 2) User name will be wildcat\(your Blackboard userID)
 * 3) Select OK
 * 4) Enter your Blackboard password.
 * 5) You should now login to a desktop.
