Hi Gerald,

Thanks for the patches.

Today I've merged a first version of the xauth-radius backend to the
master branch. I've used a slightly different approach by integrating
the xauth-radius backend directly into the eap-radius plugin. This
avoids duplicating a lot of code, and allows us to reuse all the RADIUS
goodies we already have, such as Accounting or assignment of virtual IPs
and other attributes.

Support for Access-Challenges is still missing. There are some other
changes in the pipeline though, such as multiple XAuth rounds [1], for
example to authenticate with Password and HOTP/TOTP. These won't make it
into 5.1.0, I'd like to avoid larger changes as the release is coming

Best Regards
