Red Hat Summit6장. Configuring smart card authentication with local certificates
To configure smart card authentication with local certificates:
- The host is not connected to a domain.
- You want to authenticate with a smart card on this host.
- You want to configure SSH access using smart card authentication.
-
You want to configure the smart card with
authselect.
Use the following configuration to accomplish this scenario:
Obtain a user certificate for the user who wants to authenticate with a smart card. The certificate should be generated by a trustworthy Certification Authority used in the domain.
If you cannot get the certificate, you can generate a user certificate signed by a local certificate authority for testing purposes,
- Store the certificate and private key in a smart card.
- Configure the smart card authentication for SSH access.
If a host can be part of the domain, add the host to the domain and use certificates generated by Active Directory or Identity Management Certification Authority.
For details about how to create IdM certificates for a smart card, see Configuring Identity Management for smart card authentication.
6.1. Prerequisites
Authselect installed.
The
authselecttool configures user authentication on Linux hosts and you can use it to configure smart card authentication parameters. For details about authselect, see Explaining authselect.Supported Smart Card or USB devices.
For details, see Smart Card support in RHEL.
