I have done my VPN user authentication with user database on AD via ACS. The version of ACS appliance is 220.127.116.11 on 1120 platform.
All configuration done, but problem arises when user first time authenticates, I got message in ACS in failed attempts as " Internal Error"
After repeated user attempts say three attempts, My user successfullly authenticates. When I check On ASA for failure Logs I get AAA as FAILED and then in next two three atempts it changes AAA as ACTIVE
My AD structure is WIN2k8 and remote agent version is 18.104.22.168 installed on domain controller.
You will want to set the detail level to full under System Configuration -> Service Control and restart the services, then test authentications again, download a package.cab file from System Configuration -> Support and inspect the file auth.log.
