Over the past few years I've configured several ASA's to authenticate against a Microsoft Network Policy Server using the WebVPN SVC and a aaa server group. I'm doing another one now and the CLI has changed a bit which is where I think my problems are at. The Cisco device looks good and will work fine with a local login as long as I don't try to apply my aaa server group to it's authentication. The windows server registers that the user has successfully logged in but the Cisco says it's failed. This happens when I try to login from the web vpn page and from the test button in the ASDM aaa server groups.
I'm breaking down my configurations for easier reading and leaving full copy of my configs below. If you have any questions please let me know.
To get started here is the commands I'm running to apply the aaa server group to the WebVPN.
Code:
aaa-server WindowsNPS protocol radius
aaa-server WindowsNPS (Inside) host 192.168.3.2
key <shared key>
radius-common-pw <shared key>
tunnel-group DefaultWEBVPNGroup general-attributes
authentication-server-group WindowsNPS
authentication-server-group (Inside) WindowsNPS
Here is the complete configuration for the ASA.

The Windows Server 2008 R2 server registers the incoming authentication and records it in the following order. Note that I'm breaking down each log into a individual entry and that all of this occurs one right after the other.
Code:
1:
The computer attempted to validate the credentials for an account.
Authentication Package: MICROSOFT_AUTHENTICATION_PACKAGE_V1_0

This event is generated when a process attempts to log on an account by explicitly specifying that account’s credentials. This most commonly occurs in batch-type configurations such as scheduled tasks, or when using the RUNAS command.

This event is generated when a logon session is created. It is generated on the computer that was accessed.
The subject fields indicate the account on the local system which requested the logon. This is most commonly a service such as the Server service, or a local process such as Winlogon.exe or Services.exe.
The logon type field indicates the kind of logon that occurred. The most common types are 2 (interactive) and 3 (network).
The New Logon fields indicate the account for whom the new logon was created, i.e. the account that was logged on.
The network fields indicate where a remote logon request originated. Workstation name is not always available and may be left blank in some cases.
The authentication information fields provide detailed information about this specific logon request.
- Logon GUID is a unique identifier that can be used to correlate this event with a KDC event.
- Transited services indicate which intermediate services have participated in this logon request.
- Package name indicates which sub-protocol was used among the NTLM protocols.
4:
Special privileges assigned to new logon.

This event is generated when a logon session is destroyed. It may be positively correlated with a logon event using the Logon ID value. Logon IDs are only unique between reboots on the same computer.
