Red Hat Summit7.4. Configuring your system to enforce smart card authentication
The authselect tool enables you to configure smart card authentication on your system and to disable the default password authentication. The authselect command includes the following options:
-
with-smartcard— enables smart card authentication in addition to password authentication -
with-smartcard-required— enables smart card authentication and disables password authentication
The with-smartcard-required option only enforces exclusive smart card authentication for login services, such as login, gdm, xdm, kdm, xscreensaver, gnome-screensaver, and kscreensaver. Other services, such as su or sudo for switching users, do not use smart card authentication by default and will continue to prompt you for a password.
Prerequisites
- Smart card contains your certificate and private key.
- The card is inserted into the reader and connected to the computer.
-
The
authselecttool is installed on your local system.
Procedure
Enter the following command to enforce smart card authentication:
# authselect select sssd with-smartcard with-smartcard-required --force注記Once you run this command, password authentication will no longer work and you can only log in with a smart card. Ensure smart card authentication is working before running this command or you may be locked out of your system.
