>you've configured inner-tunnel for EAP - but do you have the
inner-tunnel virtual server config file living >in sites-enabled/ ?
Hello Alan,
Here are the contents of the inner-tunnel file located in sites-enabled/

# requests for EAP-TTLS and PEAP types.

# Un-comment the next section to perform test on the inner tunnel #
without needing an outer tunnel session. The tests will not be #
exactly the same as when TTLS or PEAP are used, but they will # be
close enough for many tests.

# Authorization. First preprocess (hints and huntgroups files), # then
realms, and finally look in the "users" file.
#
# The order of the realm modules will determine the order that # we
try to find a matching realm.
#
# Make *sure* that 'preprocess' comes before any realm if you # need
to setup hints for the remote radius server authorize {
#
# The chap module will set 'Auth-Type := CHAP' if we are
# handling a CHAP request and Auth-Type has not already been
set
chap
#
# If the users are logging in with an MS-CHAP-Challenge
# attribute for authentication, the mschap module will find
# the MS-CHAP-Challenge attribute, and add 'Auth-Type :=
MS-CHAP'
# to the request, which will cause the server to then use
# the mschap module for authentication.
mschap

# Pull crypt'd passwords from /etc/passwd or /etc/shadow,
# using the system API's to get the password. If you want
# to read /etc/passwd or /etc/shadow directly, see the

# Look for IPASS style 'realm/', and if not found, look for
# '@realm', and decide whether or not to proxy, based on
# that.

# If you are using multiple kinds of realms, you probably
# want to set "ignore_null = yes" for all of them.
# Otherwise, when the first style of realm doesn't match,
# the other styles won't be checked.
#
# Note that proxying the inner tunnel authentication means
# that the user MAY use one identity in the outer session
# (e.g. "anonymous", and a different one here
# (e.g. "user at example.com"). The inner session will then be
# proxied elsewhere for authentication. If you are not
# careful, this means that the user can cause you to forward
# the authentication to another RADIUS server, and have the
# accounting logs *not* sent to the other server. This makes
# it difficult to bill people for their network activity.

# ntdomain
#
# The "suffix" module takes care of stripping the domain
# (e.g. "@example.com") from the User-Name attribute, and the

# If you want the inner tunnel request to be proxied, delete
# the next few lines.

# This module takes care of EAP-MSCHAPv2 authentication.
#
# It also sets the EAP-Type attribute in the request
# attribute list to the EAP type from the packet.
#
# The example below uses module failover to avoid querying all
# of the following modules if the EAP module returns "ok".
# Therefore, your LDAP and/or SQL servers will not be queried
# for the many packets that go back and forth to set up TTLS
# or PEAP. The load on those servers will therefore be
reduced.

# If no other module has claimed responsibility for
# authentication, then try to use PAP. This allows the
# other modules listed above to add a "known good" password
# to the request, and to do nothing else. The PAP module

# authentication.

# This module should be listed last, so that the other modules
# get a chance to set Auth-Type for themselves.

# This section lists which modules are available for authentication.
# Note that it does NOT mean 'try each module in order'. It means #
that a module from the 'authorize' section adds a configuration #
attribute 'Auth-Type := FOO'. That authentication type is then # used
to pick the apropriate module from the list below.
#
# In general, you SHOULD NOT set the Auth-Type attribute. The server #
will figure it out on its own, and will do the right thing. The # most
common side effect of erroneously setting the Auth-Type # attribute is
that one authentication method will work, but the # others will not.
#
# The common reasons to set the Auth-Type attribute by hand # is to
either forcibly reject the user, or forcibly accept him.

# The example policy below updates the outer tunnel reply
# (usually Access-Accept) with the User-Name from the inner
# tunnel User-Name. Since this section is processed in the
# context of the inner tunnel, "request" here means "inner
# tunnel request", and "outer.reply" means "outer tunnel
# reply attributes".
#
# This example is most useful when the outer session contains
# a User-Name of "anonymous at ....", or a MAC address. If it
# is enabled, the NAS SHOULD use the inner tunnel User-Name
# in subsequent accounting packets. This makes it easier to
# track user sessions, as they will all be based on the real
# name, and not on "anonymous".
#
# The problem with doing this is that it ALSO exposes the
# real user name to any intermediate proxies. People use
# "anonymous" identifiers outside of the tunnel for a very
# good reason: it gives them more privacy. Setting the reply
# to contain the real user name removes ALL privacy from
# their session.
#
# If you want privacy to remain, see the
# Chargeable-User-Identity attribute from RFC 4372. In order
# to use that attribute, you will have to allocate a
# per-session identifier for the user, and store it in a
# long-term database (e.g. SQL). You should also use that
# attribute INSTEAD of the configuration below.

# proxy accounting packets as part of normal processing.
# Then, if the home server goes down, accounting packets can
# be logged to a local "detail" file, for processing with
# radrelay. When the home server comes back up, radrelay
# will read the detail file, and send the packets to the
# home server.
#
# With this configuration, the server always responds to
# Accounting-Requests from the NAS, but only writes
# accounting packets to disk if the home server is down.
