We are planning to use our ACS server to act as a Radius Server. Our ACS is on Windows 2003 Server running V4.1 used for Tacacs+ .
I would like to know if ACS is to act as a Radius server what kind of issues do we expect?
looking for some related information on capabilities of ACS caveats and pitfalls vs advantages of this approach?
ACS can act as both as RADIUS and TACACS server,
when you say what kind of issues to expect: you need to check for open caveats in the release notes of ACS 4.1.
