To configure smart card redirection on a RHEL 8.x virtual machine (VM), install the libraries on which the feature depends, the root CA certificate to support the trusted authentication of smart cards, and the required PC/SC Lite library.
Procedure
- Install the required libraries.
yum install -y opensc pcsc-lite pcsc-lite-libs pcsc-lite-ccid nss-tools
- Enable the pcscd service.
systemctl enable pcscd
systemctl start pcscd
- Make sure that the /etc/sssd/sssd.conf configuration file contains the following lines, which enable smart card authentication.
[pam]
pam_cert_auth = True
- Copy the required CA certificate to /etc/sssd/pki/sssd_auth_ca_db.pem.
openssl x509 -inform der -in certificate.cer -out certificate.pem
cp certificate.pem /etc/sssd/pki/sssd_auth_ca_db.pem
- To verify the status of the smart card, run the following pkcs11-tool commands and confirm that they return the correct output.
pkcs11-tool -L
pkcs11-tool --login -O
pkcs11-tool --test --login
- Set up the PKCS11 module.
cp libcmP11.so /usr/lib64/
- Create the /usr/share/p11-kit/modules/libcmP11.module file. Add the following content to the file.
# This file describes how to load the opensc module
# See: http://p11-glue.freedesktop.org/doc/p11-kit/config.html
# This is a relative path, which means it will be loaded from
# the p11-kit default path which is usually $(libdir)/pkcs11.
# Doing it this way allows for packagers to package opensc for
# 32-bit and 64-bit and make them parallel installable
module: /usr/lib64/libcmP11.so

- Update PC/SC Lite to version 1.8.8.

- Install the Horizon Agent package, with smart card redirection enabled.
sudo ./install_viewagent.sh -m yes
- Restart the virtual machine and log back in.
