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.


Integrate a RHEL 8.x Virtual Machine with Active Directory for Smart Card Redirection


  1. Install the required libraries.
    # yum install -y opensc pcsc-lite pcsc-lite-libs pcsc-lite-ccid nss-tools
  2. Enable the pcscd service.
    # systemctl enable pcscd
    # systemctl start pcscd
  3. Make sure that the /etc/sssd/sssd.conf configuration file contains the following lines, which enable smart card authentication.
    pam_cert_auth = True
  4. 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
  5. 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
  6. Set up the PKCS11 module.
    cp /usr/lib64/
  7. 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:
    # 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/
    priority: 99
  8. Update PC/SC Lite to version 1.8.8.
    # yum install -y git flex autoconf automake libtool libudev-devel flex
    # git clone
    # cd PCSC
    # git checkout -b pcsc-1.8.8 1.8.8
    # ./bootstrap
    # ./configure --build=x86_64-redhat-linux-gnu --host=x86_64-redhat-linux-gnu 
         --program-prefix= --disable-dependency-tracking --prefix=/usr --exec-prefix=/usr 
         --bindir=/usr/bin --sbindir=/usr/sbin --sysconfdir=/etc --datadir=/usr/share 
         --includedir=/usr/include --libdir=/usr/lib64 --libexecdir=/usr/libexec 
         --localstatedir=/var --sharedstatedir=/var/lib --mandir=/usr/share/man 
         --infodir=/usr/share/info --disable-static --enable-usbdropdir=/usr/lib64/pcsc/drivers
    # make
    # make install
  9. Install the Horizon Agent package, with smart card redirection enabled.
    # sudo ./ -m yes
  10. Restart the virtual machine and log back in.
