  1. Change into the /etc/raddb/certs directory

    Code Block
    languagebash
    linenumberstrue
    cd /etc/raddb/certs


  2. Edit the certificate generation properties in client.cnfserver.cnf, and ca.cnf as follows:

    1. In the ca.cnf file:
      1. In the [ req ] section, add encrypt_key = no
      2. In the [CA_default] section, change the default_days from 60 to a higher number (this is how long the certificates you create will be valid for). When the certificates expire, you will have to recreate them.

      3. in the [ certificate_authority ] section, change all of the parameters to match those of your organisation. e.g.

        Code Block
        linenumberstrue
        [certificate_authority]
        countryName             = GB
        stateOrProvinceName     = England
        localityName            = Camford
        organizationName        = Camford University
        emailAddress            = support@camford.ac.uk
        commonName              = "Camford University FR Certificate Authority"


    2. In the server.cnf file:

      1. In the [ req ] section, add encrypt_key = no
      2. In the [CA_default] section, change the default_days from 60 to a higher number (this is how long the certificates you create will be valid for). When the certificates expire, you will have to recreate them.
      3. in the [ server ] section, change all of the parameters to match those of your organisation. e.g.

        Code Block
        linenumberstrue
        [server]
        countryName             = GB
        stateOrProvinceName     = England
        localityName            = Camford
        organizationName        = Camford University
        emailAddress            = support@camford.ac.uk
        commonName              = "Camford University FR Server Certificate"


        Warning

        When changing passwords in the [ req ] section of the server.cnf file, you must also update the private_key_password option in the FreeRADIUS mods-available/eap file with the same password.

        We recommend that you do not change these defaults.


    3. In the client.cnf file:

      1. In the [ req ] section, add encrypt_key = no
      2. In the [CA_default] section, change the default_days from 60 to a higher number (this is how long the certificates you create will be valid for). When the certificates expire, you will have to recreate them.
      3. in the [ client ] section, change all of the parameters to match those of your organisation. e.g.

        Code Block
        linenumberstrue
        [client]
        countryName             = GB
        stateOrProvinceName     = England
        localityName            = Camford
        organizationName        = Camford University
        emailAddress            = support@camford.ac.uk
        commonName              = "Camford University FR Client Certificate"


        Note
        All of the organisation parameters (countryName, localityName, etc) need to match in the three .cnf files but the commonName must be unique in each file)


  3. Clear out any old certificates in the directory:

    Code Block
    languagebash
    linenumberstrue
    make destroycerts


  4. Run the bootstrap script to generate the certificates

    Code Block
    languagebash
    linenumberstrue
    ./bootstrap


  5. Create a file that is the concatenation of the certificate and private key of the client.

    Code Block
    languagebash
    linenumberstrue
    openssl x509 -in client.crt > client.pem ; cat client.key >> client.pem


  6. Because the above command was run as root, the keys and certificates created will not be readable by the FreeRADIUS user by default, and FreeRADIUS will not be able to start. To fix this, reset the group for the files:

    Code Block
    languagebash
    linenumberstrue
    chgrp radius {client,* server,* ca,* dh}*


RadSec

Next, we need to configure RadSec. We do this by creating a file at /etc/radsec.conf with the following:
