You're probably talking about using MySQL-Proxy which is doing pretty much the same thing as FreeRADIUS. It's your choice whether you want to manage the failover using FreeRADIUS or another local service.

AFAIK MySQL cluster (NDB) itself does not have the option have have floating IP addresses. But I may be wrong, it's been a while since i've tried MySQL cluster. Could you point me to the documentation that says it does this?

Yes use Git to clone the GitHub repository.

Sure it works OK. I've compiled from source a couple of times without issues. See here: for additional help (Use OpenCSW to get the relevant libraries and build tools -

There's also an SMF manifest in the scripts dir, if you want to manage FreeRADIUS from svcadm.
