Not able to receive inner identity in Access-Accept in EAP-TTLS.

Hi Team,
I am using freeradius version 2.1.12.
I have configured following in the eap.conf file in the ttls section :
copy_request_to_tunnel = yes
use_tunneled_reply = yes
virtual_server = "inner-tunnel"
and in the inner-tunnel file i have configured following :
post-auth {
....
update outer.reply {
User-Name := "%{Stripped-User-Name}"
}
I am able to get the inner identity in Access-Accept if I use PEAP with
MS-CHAPv2, but I am not getting inner identity in Access-Accept if I use
EAP-TTLS.
Please find the eap.conf, inner-tunnel and free_radius.log files in the
attachment.
File free_radius.log has logs of EAP-TTLS method only. I am using
'testuser' as inner identity and 'anonymous' as outer identity(anonymous
identity).
Please provide your inputs on this.
Thanks,
Bhavesh.

#
# Whatever you do, do NOT set 'Auth-Type := EAP'. The server
# is smart enough to figure this out on its own. The most
# common side effect of setting 'Auth-Type := EAP' is that the
# users then cannot use ANY other authentication method.
#
# EAP types NOT listed here may be supported via the "eap2" module.
# See experimental.conf for documentation.
#
eap {
# Invoke the default supported EAP type when
# EAP-Identity response is received.
#
# The incoming EAP messages DO NOT specify which EAP
# type they will be using, so it MUST be set here.
#
# For now, only one default EAP type may be used at a time.
#
# If the EAP-Type attribute is set by another module,
# then that EAP type takes precedence over the
# default type configured here.
#

# packets with EAP-Request packets. After a
# configurable length of time, entries in the list
# expire, and are deleted.
#
timer_expire = 60
# There are many EAP types, but the server has support
# for only a limited subset. If the server receives
# a request for an EAP type it does not support, then
# it normally rejects the request. By setting this
# configuration to "yes", you can tell the server to
# instead keep processing the request. Another module
# MUST then be configured to proxy the request to
# another RADIUS server which supports that EAP type.
#
# If another module is NOT configured to handle the
# request, then the request will still end up being
# rejected.

# We do not recommend using LEAP in new deployments. See:

# Cisco LEAP uses the MS-CHAP algorithm (but not
# the MS-CHAP attributes) to perform it's authentication.

# User-Password, or the NT-Password attributes.
# 'System' authentication is impossible with LEAP.

# Currently, this is only permitted inside of EAP-TTLS,

#
# Proxying the tunneled EAP-GTC session is a bad idea,
# the users password will go over the wire in plain-text,
# for anyone to see.

# 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.

# See raddb/certs/README for additional comments
# on certificates.
#
# If OpenSSL was not found at the time the server was
# built, the "tls", "ttls", and "peap" sections will
# be ignored.
#
# Otherwise, when the server first starts in debugging
# mode, test certificates will be created. See the
# "make_cert_command" below for details, and the README
# file in raddb/certs
#
# These test certificates SHOULD NOT be used in a normal
# deployment. They are created only to make it easier
# to install the server, and to perform some simple
# tests with EAP-TLS, TTLS, or PEAP.

# 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.

# The main use of this section is to permit robust proxying
# of accounting packets. The server can be configured to
# 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.
