If they're your users, then you should authenticate them. You don't need to edit the User-Name. You don't need to proxy. Describe the problem you're trying to solve.
We are a small entity next to a big university. The neighbouring university allows its users to connect to eduroam locally without specifying the realm in the username, but this can lead to problems because their users are often not aware that they need to use the full username if they wish to roam.
That is exceptionally bad behaviour. You should have a word with the uni next door, and if necessary, get eduroam UK (i.e. Jisc) involved to get them to prod the uni into sticking to protocol (which is that you use the full email-address-style username/NAI).
We get many visitors from the university and their perception is that our wireless is broken. I want to make it easier for those visitors to connect to eduroam, because I can't explain to all visitors that they
That's bad behaviour. It only lets them continue their bad behaviour which then causes the same problems elsewhere (wherever they encounter eduroam). As much as it is 'not my problem'(TM), having a word with the IT department at the uni can resolve this better.
should user their full username. I need to proxy and I think that need to add the realm to the username, otherwise the eduroam NRPS won't know what to do with the request.
Well, precisely. The NRPS follows eduroam protocols, as should the university in question.
