3.5. Adding a new user automatically mapped to the SELinux unconfined_u user

Procedure

1. Enter the following command to create a new Linux user named <example_user>:

   # useradd <example_user>

2. To assign a password to the Linux <example_user> user:

   # passwd <example_user>
   Changing password for user <example_user>.
   New password:
   Retype new password:
   passwd: all authentication tokens updated successfully.

3. Log out of your current session.
4. Log in as the Linux <example_user> user. When you log in, the pam_selinux PAM module automatically maps the Linux user to an SELinux user (in this case, unconfined_u), and sets up the resulting SELinux context. The Linux user’s shell is then launched with this context.

Verification

1. When logged in as the <example_user> user, check the context of a Linux user:

   $ id -Z
   unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023
