Creating a user for ts-shell

You must create one or more users for ts-shell.

1. Create a user with ts-shell as the login shell and user group ts-shell.
   Example:

   [root]# useradd -s /usr/bin/ts-shell -G ts-shell alice

   Note: Ensure that the new user does not acquire any unintended authorizations from being added to default user groups. Adding the new user to the ts-shell group does not affect membership of such groups.
   You can change an existing user ID to use ts-shell as the login shell and add the user to the ts-shell group by issuing a command of this form:

   [root]# usermod -a /usr/bin/ts-shell -G ts-shell <id>

   where <id> is the existing ID.
2. Optional: You might want to add the user to additional user groups to manage access to target systems.
3. Set an initial password for the new user and force the new user to change the password at the initial login.
   Example:

   [root]# passwd alice
   ...
   [root]# chage alice
