Hi,
Please find the <<eap.conf>> attached with this Email. This is file which
i am using for testing MS-CHAPV2 over TTLS.
I am not sure what is wrong with this configuration.
Thanks in advance.

we've had no problem with EAP-TTLS with MSCHAPv2 - you cant play with
User-Name etc - just ensure you are allowing the reply to be tunneled
in eap.conf.
however, if you try changing reply attributes (eg VLAN) then it doesnt
work - should be fixed in 1.1.5
