VPN / RADIUS question

I have a small network which I maintain...I've set up the following -

- 1 Windows 2003 Domain Controller (1 DC)
- 1 Server as a File Server / VPN Server (Windows 2003 RRAS)

The VPN and everything works fine - it authenticates to AD (the DC).

From the things I've read, you need a RADIUS (IAS) server in order for the
VPN Server to authenticate VPN users against the Domain Controller for the
domain.

Now, I never installed RADIUS in this simple environment, but my File Server
/ VPN server still authenticate domain users against the Domain Controller.

Why is my solution working and authenticating domain users when I do not
have a RADIUS per documentations and reading materials I've read.

Can someone please elaborate on this more...thank you.
 
No, that isn't so. You only need RADIUS if the RRAS device is not Windows.
If the RRAS device is a Windows server, the authentication to AD is handled
by Windows. The RRAS server becomes a member of the IAS and RAS server
group, and authentication is done against the AD database. You set the RRAS
server to use Windows authentication, not RADIUS.
