[c-nsp] Open Source solution to deploy a radius server against Cisco devices?

[luismi]

Hi all,

I am looking for an open source solution to deploy some radius in our
network.
The primary goal is to connect to those radius to provide auth services:
- The VPN Concentrators and vpn accounts (we would move all the vpn
accounts info to the radius)
- Validate ip http auth-proxy users

Radius service should be able to be managed using a web interface.
I don't really mind if there is a proper web interface of if we need to
install webadmin.
It also must support accounting.
And it would be great if it is possible to have the back-end into MySQL.

I was checking FreeRadius and Radiator.
Any other options?
All comments are welcome.

Thanks
