CAC Reader Installation Guide
CAC Reader Installation Guide
Installing a CAC (Common Access Card) reader can be straightforward if you follow these steps. Whether on Windows, Mac, or Linux, the process is slightly different for each. This guide will help you through each step to ensure successful installation and enable use of your CAC reader and card.
Prerequisites
- A working CAC reader
- Latest drivers for your CAC reader
- Your CAC card
- Admin rights on your computer
- Stable internet connection
Windows Installation
First, connect your CAC reader to your computer via USB. Wait for Windows to detect and recognize the device. Sometimes Windows can install generic drivers automatically, but it’s better to use the latest drivers from the manufacturer.
Installing Drivers
Go to the official website of your CAC reader manufacturer. Download the latest driver for your model and operating system. Open the downloaded file and follow the installation prompts. The installer will place the necessary files and configure your system.
Configuring Middleware
Middleware is necessary for your computer to communicate with the CAC reader. Download and install middleware such as ActivClient. Follow the prompts during installation. After installation, restart your computer to apply changes.
Testing the Reader
- Insert your CAC card into the reader.
- Open a web browser and go to a CAC-enabled website such as DMDC Self-Service.
- When prompted, select your certificate and enter your PIN.
If you gain access, your CAC reader is functioning correctly.
Mac Installation
Plug in your CAC reader and wait for your Mac to detect it. Unlike Windows, Mac does not have built-in support for CAC readers. This requires additional drivers and software.
Installing Drivers
Similar to Windows, go to the CAC reader manufacturer’s website. Download the latest drivers and middleware for macOS. Open the downloaded files and follow the installation instructions. You might need to allow the installation in your System Preferences under Security & Privacy.
Configuring Middleware
For Mac, middleware options include CACKey and PKard. Download and install the desired middleware based on your usage and personal preference. For CACKey, you can find it on the MilitaryCAC website. Follow the installation prompts and restart your Mac after the installation is complete.
Testing the Reader
- Insert your CAC card into the reader.
- Open Safari or Chrome and go to a CAC-enabled site like the DMDC Self-Service.
- Select your certificate when prompted and enter your PIN.
If you have access, your CAC reader is properly set up.
Linux Installation
Not as user-friendly as Windows and Mac, installing a CAC reader on Linux requires more terminal interaction. Yet, it is achievable by following these steps.
Install Required Packages
Open a terminal and execute the following commands to install the necessary tools:
sudo apt-get update
sudo apt-get install pcscd pcsc-tools pcscscan libpcsclite-devInstalling Drivers
Most Linux distributions support CCID-compliant CAC readers natively. For specific models, download drivers from the manufacturer’s site and follow their installation instructions, which usually involve extracting and compiling the drivers.
Configuring Middleware
OpenSC provides an interface for smart cards on Linux. Install OpenSC using:
sudo apt-get install openscEdit the configuration file /etc/opensc/opensc.conf if necessary to ensure it supports your card reader and card type.
Testing the Reader
- Insert your CAC card into the reader.
- Open a terminal and type
pcsc_scanto ensure the reader detects the card. - To test in a browser, open Firefox and visit a CAC-enabled site.
- Select your certificate and enter your PIN.
If you access the site, your CAC reader setup is successful.
Troubleshooting
Driver Issues
If your computer doesn’t recognize the device, ensure the correct driver is installed. Manually updating the driver can resolve detection issues. Even when updating automatically, it’s helpful to recheck the manufacturer’s site for newer releases.
Middleware Conflicts
If you experience certificate or card reading errors, conflicts between different middleware applications might be the cause. Uninstall existing middleware before installing another version to avoid clashes.
Browser Settings
CAC authentication often requires specific browser settings. Ensure that plugins and security settings allow certificate-based logins. Firefox users may need to import the DoD certificates manually and configure Security Devices under the browser’s settings.
