Windows Domain SSH

• Install Cygwin, for openssh you only need the openssh package but a few other tools will probably help(vim,wget,shutdown,rsync)
• Create a service domain account that we will used to be able to login through ssh from a domain joined computer

• Making the passwd file for Domain users:

mkpasswd -d > /etc/passwd
mkgroup -g > /etc/group

• Making the passwd file for local users:

mkpasswd -cl > /etc/passwd
mkgroup -cl > /etc/group

• Now you'll need to edit the passwd file and remove the hostname and/or domain name from the beginning of each user you'd like to be able to ssh into the system with.

• on the local computer we need to add the Domain service account to certain groups
• Go to Administrative tools in the Control Panel and open the Local Security Policy
• Navigate to

Local Security Policy => Security Settings => Local Policies => User Rights Assignment 

• add domain user to these groups

Act as part of the operating system
Create a token object
Deny log on through remote desktop services
Log on as a service
Replace a process level token

• Setup sshd

ssh-host-config

• We are going to answer yes to most of the default configuration, Except we will replace the user which is the service account used to run cygwin
• By default it creates this user under the name cyg_server, when asked if we would like to create this user we will say no and give the ssh-host-config script another user which has the appropriate permission to allow domain logins
• In our domain the user created for this purpose is cyg_service
• below shows a summary of what we will be saying yes and no too as long as with output from a setup

Should privilege separation be used(yes/no)? Yes
