I have a ACS Appliance running version 4.2 ==> ACS 126.96.36.199.12-Fix where the function is just for authenticate users by
protocol RADIUS against a Active Directory - Microsoft.
The Remote Agents are running, AAA Clients and Server are OK and the External User Database (AD TREE) are mapped.
When starting a authentication it doesn't work and in the FAILED ATTEMPS ACTIVE, the AUTHENTICATION CODE FAILURE is " INTERNAL ERROR "
Which tests can i perform ?
I doesn't found good documentations about " INTERNAL ERROR "
