Hi,

I would use:

server)
realm DEFAULT {
pool = EDUROAM-FTLR
nostrip

hmmmm, this isnt best practice if thats all you have for throwing stuff
upstream. woulf
strongly recommend using unlang to validate that the user has valid realm
etc and then
update the request to use a realm identifier (eg eduroam) and use that in
proxy.conf instead -
thus you are only sending valid users upstream (and not all the random
typos and junk)
as the upstream servers will like you more for that - and wont be dropping
requests and messing
you up.
To expand on Alan's statement a bit here - it's possible that users are
associating with your eduroam SSID and sending all kinds of nonsense (I think
the best I've seen is:
<space>user@domain<newline><space>user@domain</newline><repeat 3 times>
...and that the upstream RADIUS servers are not replying, which is causing
you to get these dropouts.
You probably want something like this:
authorize {
if (User-Name =~ /^([^@]*)@([-A-Z0-9]+(\\.[-A-Z0-9]+)+)$/) {
# user has a valid-looking realm
update request {
Stripped-User-Name := "%{1}"
Realm = "%{toupper:%{2}}"
}
}
else {
# malformed NAI
update reply {
Reply-Message := "malformed username"
}
reject
}
if (Realm == MY.REALM) {
...
}
else {
update control {
Proxy-To-Realm := DEFAULT
}
}
This looks like something I should be doing but I have no idea where to
insert this section. Is it in proxy.conf or somewhere else? And that last
section for my own realm, would it look like this (you're converting the
Realm to upper case, right?)
if (Realm == MY.REALM) {
update control {
Proxy-To-Realm := MY.REALM
}
}
else {
update control {
Proxy-To-Realm := DEFAULT
}
}
With this configuration, I guess I don't need realm's LOCAL or NULL?
