Hello Community,
I had created the attached example a while ago for ACS 5.x and PEAP Authentication. I hope this becomes a useful document for people looking for guidance on how to accomplish this.
NOTE: I assumed that the ACS 5.x has been successfully joined to a Windows AD for External Accounts validation already.
Regards,
Carlos Mejia
