MIRACL Trust RADIUS is a RADIUS server implementing authentication, authorization and accounting. It could be configured to communicate with one or more RADIUS-supporting clients so they gain access to a particular network resource using One Time Passwords (OTPs) generated from the MIRACL Trust authentication platform. You could generate OTPs either by visiting your saved OTP url in your web browser or by your mobile app connected to the MIRACL Trust authentication platform. They will be valid for a default of 90 seconds. MIRACL Trust RADIUS could be configured to authenticate using one of the following authentication mechanisms - PAP, CHAP, MSCHAPv1 and PEAPv0-MSCHAPv2 which allows you to authenticate through a secure tunnel.
Once installed, the use of MIRACL Trust RADIUS involves managing a set of config files which are located in the
The steps involved are:
Create a new MIRACL Trust RADIUS app in the MIRACL Trust authentication portal to receive the Client ID and Client Secret needed to set up the connection between your instance and the authentication portal, and to generate a url at which your end users can generate OTPs to register and authenticate
Install your MIRACL Trust RADIUS server
Configure your MIRACL Trust RADIUS server and RADIUS client / VPN server (simple ssh client, OpenVPN, Cisco Anyconnect etc.)
End users can then visit the OTP generation url in their browser or use the MIRACL Trust mobile app to generate One Time Passwords (associated with the same email they registered with in step 2) which allow them to login to the RADIUS client / VPN server
Once installed, MIRACL Trust RADIUS is configured for use by YAML configuration files stored in the
/etc/miracl-radius/ directory. Note that the default example layout and naming of the config files is only for guidance, and you can choose a different structure and naming system and describe it in the
include section of the main
config.yaml file. Also the configuration files could be in either json or yaml format.
/etc/miracl-radius/ ├── config.yaml ├── core.yaml ├── hosts │ └── example.yaml │ └── fortigate.yaml │ └── openvpn.yaml │ └── sshtest.yaml └── integrations ├── accounting.yaml ├── ldap.yaml ├── log.yaml ├── peap.yaml ├── redis.yaml ├── stats.yaml └── mfa.yaml
The config.yaml file simply lists the other files to be included. The following example shows that you are only including
includes: - core.yaml # - hosts/example.yaml - hosts/openvpn.yaml # - hosts/sshtest.yaml # - integrations/log.yaml - integrations/ldap.yaml # - integrations/mfa.yaml # - integrations/peap.yaml # - integrations/redis.yaml # - integrations/stats.yaml
core.yaml contains the basic details of your MIRACL Trust RADIUS installation, plus the Client ID and Client Secret obtained from the admin portal.
In the hosts/ subfolder, you can configure multiple hosts for OTP access (ssh clients, VPN clients, etc.)
Note that settings in files lower down the list of includes will override settings in those higher in the list. For example if you include a file which specifies a server port number, this will override a server port number set in a file higher in the list of includes.
MIRACL Trust RADIUS server has a configuration dump functionality which allows you to see the full config settings which your server will be started with. You could just run the server with
-d option and specify which format you'd like to see the full configuration. The following command will output in yaml format the assembled configuration the server will be run with that config file:
$ ./miracl-radius -c ./config.yaml -d yaml
When changes have been made to your MIRACL Trust RADIUS config files (in the
/etc/miracl-radius/ directory) it is necessary to restart the service so changes could apply.
