Client Compatibility with PEAP and Certificates

24 Sep 2019

      Hello All,

I've recently setup FreeRADIUS 3.0.17 using MySQL (Mariadb) together with phpMyAdmin all running on a Raspberry Pi 3. I'm using FreeRADIUS to send Mikrotik attributes to my NAS for my PEAP authenticated wireless clients which works well.

I'm now moving to a production setup for a community, so I've obtained new certificates (DomainSSL) which have been issued by 'GoGetSSL'.

To do this, I've updated the 'snake-oil' certificates, including the 'private key' and 'server.crt' provided by the certificate issuer. With regard to the 'Trusted root CA' certificates', I've combined both the 'USERTrust_RSA_Certificate_Authority.crt' and 'AddTrustExternal_CA_Root.crt' into one file and updated the ./etc/mods-enabled/eap to use my keys and certificates.

The issue I'm having is that when using my updated certificates and authenticating my wireless clients via PEAP, some devices such as my Macbook Air (MacOS Mojave) mark the certificates as valid while others, such as my iPhone (iOS 12) mark the certificate as invalid. I believe this issue relates to the root trust certificate?

What could I do to improve compatibility and prevent this invalid certificate issue for my end users? Could this be solved by using a different certificate provider? such as LetsEncrypt with a public CA?

With Thanks,

Shan.

#  Included with the server in raddb/certs.
#
#  If these certificates have not been auto-generated:

#
#  These test certificates SHOULD NOT be used in a normal

 virtual_server = "inner-tunnel"

 # This option enables support for MS-SoH
 # see doc/SoH.txt for more info.
 # It is disabled by default.
 #
# soh = yes

 #
 # The SoH reply will be turned into a request which
 # can be sent to a specific virtual server:
 #
# soh_virtual_server = "soh-server"

 #
 # Unlike EAP-TLS, PEAP does not require a client certificate.
 # However, you can require one by setting the following
 # option. You can also override this option by setting
 #
 # EAP-TLS-Require-Client-Cert = Yes
 #
 # in the control items for a request.
 #
 # Note that the majority of supplicants do not support using a
 # client certificate with PEAP, so this option is unlikely to
 # be usable for most people.
 #
# require_client_cert = yes
}

#
#  This takes no configuration.
#
#  Note that it is the EAP MS-CHAPv2 sub-module, not
#  the main 'mschap' module.
#
#  Note also that in order for this sub-module to work,
#  the main 'mschap' module MUST ALSO be configured.
#
#  This module is the *Microsoft* implementation of MS-CHAPv2
#  in EAP.  There is another (incompatible) implementation
#  of MS-CHAPv2 in EAP by Cisco, which FreeRADIUS does not
#  currently support.
#
mschapv2 {
 #  Prior to version 2.1.11, the module never
 #  sent the MS-CHAP-Error message to the
 #  client.  This worked, but it had issues
 #  when the cached password was wrong.  The
 #  server *should* send "E=691 R=0" to the
 #  client, which tells it to prompt the user
 #  for a new password.
 #
 #  The default is to behave as in 2.1.10 and
 #  earlier, which is known to work.  If you
 #  set "send_error = yes", then the error
 #  message will be sent back to the client.
 #  This *may* help some clients work better,
 #  but *may* also cause other clients to stop
 #  working.
 #
#  send_error = no

 #  Server identifier to send back in the challenge.
 #  This should generally be the host name of the
 #  RADIUS server.  Or, some information to uniquely
 #  identify it.
#  identity = "FreeRADIUS"
}

## EAP-FAST
#
#  The FAST module implements the EAP-FAST protocol
#
# fast {
 # Point to the common TLS configuration
 #
#  tls = tls-common

 #
 #  If 'cipher_list' is set here, it will over-ride the
 #  'cipher_list' configuration from the 'tls-common'
 #  configuration.  The EAP-FAST module has it's own
 #  over-ride for 'cipher_list' because the
 #  specifications mandata a different set of ciphers
 #  than are used by the other EAP methods.
 #
 #  cipher_list though must include "ADH" for anonymous provisioning.
 #  This is not as straight forward as appending "ADH" alongside
 #  "DEFAULT" as "DEFAULT" contains "!aNULL" so instead it is
 #  recommended "ALL:!EXPORT:!eNULL:!SSLv2" is used
 #
 #  Note - for OpenSSL 1.1.0 and above you may need
 #  to add ":@SECLEVEL=0"
 #
#  cipher_list = "ALL:!EXPORT:!eNULL:!SSLv2"

 # PAC lifetime in seconds (default: seven days)
 #
#  pac_lifetime = 604800

 # Authority ID of the server
 #
 # if you are running a cluster of RADIUS servers, you should make
 # the value chosen here (and for "pac_opaque_key") the same on all
 # your RADIUS servers.  This value should be unique to your
 # installation.  We suggest using a domain name.
 #
#  authority_identity = "1234"

 # PAC Opaque encryption key (must be exactly 32 bytes in size)
 #
 # This value MUST be secret, and MUST be generated using
 # a secure method, such as via 'openssl rand -hex 32'
 #
#  pac_opaque_key = "PAC_KEY"

 # Same as for TTLS, PEAP, etc.
 #
#  virtual_server = inner-tunnel
