Prerequisites for RADIUS server

If you are a new customer, for optimum performance, especially for large enterprises, install the SecureAuth RADIUS server separately from the Identity Platform server. If in doubt, contact SecureAuth Support.

  • SecureAuth® Identity Platform version 9.3 or later

  • Hybrid: Authentication API (v9.3+) configured and enabled on the realm

  • Cloud: Authentication Apps (19.07+) configured and enabled on Identity Platform, plus Authentication API (v9.3+) configured and enabled on the realm

  • If you use a load balancer:

    When you use Push-to-Accept, Symbol-to-Accept, or Link-to-Accept MFA methods with SecureAuth RADIUS Server, you must enable session persistence ("sticky sessions") on the load balancer to maintain state with the Identity Platform. SecureAuth RADIUS Server supports cookie-based persistence only.

    You don't need to enable session persistence if RADIUS Server is installed on the Identity Platform server or is targeted directly (not load-balanced).

Supported SecureAuth Identity Platform features

See the SecureAuth compatibility guide for product and component compatibility with operating systems, Authenticate app, browsers, Java, data stores, identity types, SSO/post-authentication actions, Login for Windows, Login for Mac, and YubiKey.

Configuration notes

Adaptive Authentication


Configure threat checking for:

  • User Groups – See Adaptive Authentication for RADIUS responses with user group checking enabled.

  • End user Client IPs – Cisco, NetScaler, and Palo Alto Networks platforms only.



Attribute Mapping


Configure and enable Identity Management API (v9.3+) on the realm to grant or deny end user login access.

Group based authentication – Optionally configure Membership Connection Settings to grant or deny login access:

  • Specify the name of the user group to be granted or denied access, or

  • Designate a Property from Profile Fields to identify the user group to be granted or denied access.

Port Settings


  • Allow RADIUS Listener – Default is UDP port 1812.

  • Block TCP port 8088 – This port is used for the administrative web interface and should be blocked for security reasons.

RADIUS VPN and Product Support

The following basic connectivity parameters must be configured on RADIUS clients to be used with the Identity Platform:

  • RADIUS server IP address

  • Shared secret to use between the RADIUS server and RADIUS clients

  • Port 1812 to use for RADIUS authentication requests, and Port "0" for accounting when applicable or if used as the default port

  • Timeout value Retries value

  • Connection profile that will use the SecureAuth RADIUS authentication serverGroup policy of the connection profile to identify resources end users can access once logged on the network

A valid certificate must be installed if using NetMotion Wireless VPN.

The following is a sample RADIUS authentication server configuration:

SecureAuth Identity Platform RADIUS Server Information



RADIUS Server friendly description name

This configuration enables the administrator to control static IP assignment of the VPN client via SecureAuth Identity Platform and the RADIUS server.

NOTE: SecureAuth IdP RADIUS server v19.06 or later can be configured to pass an IP address to the VPN for static IP assignment to the VPN client (for example: PC or Mac). See SecureAuth IdP RADIUS Server Static IP Address Configuration Guide for steps.
