Hi, Finally, I have created a patch for FreeRadius to support EAP-AKA implementation. Please find the attached patch (freeradius-1.1.4_eap_aka_support.diff) in the rar file for freeradius-1.1.4 version release. I hope with small effort that can also be applied on the latest version releases as well. Apart from adding EAP-AKA support changes in patch, I have also added some fixes for EAP-Aka to handle variable RES length support. As far as configuration is concerned, there are very small changes required in "eap.conf" and "users" files to make it working and those changes are as follows 1. eap.conf a) Remove the default eap type from md5 in EAP configuration b) Add the EAP types of sim and aka along with md5 2. Users Add the user domain along with EAP types and their respective parameters for validation. I have created a patch (freeradius-1.1.4_eap_aka_support_conf.diff) for the configuration changes. Please find attached freeradius-1.1.4_eap_aka_support_conf.diff patch file in the attached rar file for the reference. Feel free to revert, in case there are some clarifications required. Thanks.
