Citrix ADC RADIUS integration
Multi-Factor Authentication (MFA) is an extra layer of security used when logging into websites or apps. Individuals are authenticated through more than one required security and validation procedure that only they know or have access to.
Remote Authentication Dial-In User Service (RADIUS) is a protocol commonly used to authenticate, authorize, and account for user access and actions.
Citrix™ ADC is an application delivery and load balancing solution that gives a high-quality user experience of web services and cloud-native applications, wherever hosted. Arculix by SecureAuth, as a Citrix Ready Partner, offers a simple method for adding MFA to Citrix ADC via its RADIUS solution.
Prerequisites
Arculix RADIUS Agent that is configured and connected to your user directory. For example, Microsoft Active Directory (AD).
For more information, see the Arculix RADIUS Agent deployment guide.
User account with administrative privileges for Citrix ADC.
Arculix RADIUS Agent configuration
To integrate Arculix with your Citrix ADC, you will need to install an Arculix RADIUS Agent on a machine within your network. This server will receive RADIUS requests from your Citrix ADC, check with the LDAP server to perform primary authentication, and then contact Arculix cloud service for secondary authentication.
Follow these steps to configure the Arculix RADIUS Agent.
Log in to the Arculix RADIUS Agent as an administrator.
Open the radius-agent-config.env file with an editor.
The file is located in the installed directory of RADIUS Agent. RADIUS clients are configured in this setting.
At the end of the radius-agent-config.env file, set the following configuration for the ARA_CLIENTS attribute:
Note
The values should be separated by semicolons (;).
Note
Subnet IP address (SNIP) is a Citrix ADC owned IP address that is used by the Citrix ADC to communicate with the backend servers.
ARA_CLIENTS = <An optional name for your ADC>; <Internal IP address of your SNIP>; <a shared secret>
For example, set:
ARA_CLIENTS = ADC;192.168.1.60/32;testing123
Save the file.
Run the following command to apply the changes:
docker-compose down && docker-compose up -d
