Configure Smart Card Redirection on a RHEL Virtual Machine

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.

Prerequisites

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

Procedure

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]
   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 libcmP11.so /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: 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
   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 https://salsa.debian.org/rousseau/PCSC.git
   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 ./install_viewagent.sh -m yes
   

10. Restart the virtual machine and log back in.
