Modified /etc/freeradius/3.0/mods-available/eap:
commented the following:
.... # md5 { # } .... # leap { # } .... # gtc { # # The default challenge, which many clients # # ignore.. # #challenge = "Password: " # # # The plain-text response which comes back # # is put into a User-Password attribute, # # and passed to another module for # # authentication. This allows the EAP-GTC # # response to be checked against plain-text, # # or crypt'd passwords. # # # # If you say "Local" instead of "PAP", then # # the module will look for a User-Password # # configured for the request, and do the # # authentication itself. # # # auth_type = PAP # } .... # tls { # # Point to the common TLS configuration # tls = tls-common # # # # # As part of checking a client certificate, the EAP-TLS # # sets some attributes such as TLS-Client-Cert-CN. This # # virtual server has access to these attributes, and can # # be used to accept or reject the request. # # # # virtual_server = check-eap-tls # } ....
modified the 'default_eap_type' directive under section 'eap' to be:
default_eap_type = peap
and the 'default_eap_type' directive under section 'ttls' to be:
default_eap_type = mschapv2

Python module / script_launcher.py script
cd /etc/freeradius/3.0/ ln -s mods-available/python mods-enabled/
Put the following in it:
# # Make sure the PYTHONPATH environmental variable contains the # directory(s) for the modules listed below. # # Uncomment any func_* which are included in your module. If # rlm_python is called for a section which does not have # a function defined, it will return NOOP. # python { module = script_launcher # @#$dy python_path = ${modconfdir}/${.:name}:/usr/lib/python2.7 # @#$dy mod_post_auth = ${.module} # @#$dy func_post_auth = post_auth # @#$dy }
Modify /etc/freeradius/3.0/sites-enabled/inner-tunnel:
... # Add this line just after 'sql' in the 'post-auth' section python ...
Modify /etc/freeradius/3.0/mods-available/eap, modified the 'copy_request_to_tunnel' directive under both sections 'peap' and 'ttls' to be:
copy_request_to_tunnel = yes
Place the script_launcher.py script at /etc/freeradius/3.0/mods-config/python/script_launcher.py

apt-get install libpam-script sshpass mkdir /usr/share/libpam-script/pam-script.d/pam_to_mysql_update cd /usr/share/libpam-script/pam-script.d/pam_to_mysql_update # Put the script in here, and configure MySQL settings inside ln -s pam_to_mysql_update.sh pam_script_auth ln -s pam_to_mysql_update.sh pam_script_passwd
Add the following line at the end of /etc/pam.d/common-auth or as may be appropriate to the PAM configuration of the system:
... auth required pam_script.so onerr=fail dir=/usr/share/libpam-script/pam-script.d/pam_to_mysql_update/
