    I would not use EAP-GTC or Termination with LDAP for Windows devices.  I would install NPS on your Windows server, instead and use Radius and MSChapV2.  The EAP-GTC shim has not been updated for years, and when things do not work with it, it is difficult to understand why.  It is also impossible to configure your clients for GTC with group policy, which means you would have to install software and touch them all individually. GTC has support with handheld mobile devices, but MAC OSX has removed it natively and Windows has no support outside of installation of additional outdated software.  When it doesn't work, LDAP doesn't provide alot of information why not.

     

    Detailed information on how to Install and configure NPS is here:  http://community.arubanetworks.com/t5/Community-Tribal-Knowledge-Base/Step-by-Step-How-to-Configure-Microsoft-NPS-2008-Radius-Server/ta-p/80672

    Hi,

     

    Thank for your suggestion. But lucky me i just find the solution. So the problem is from the client's setting, just simply uncheck validate server certificate. And it work well
