(RADIATOR) Copying inner username to Access-Accept for correct accounting

[Rok Papez]

Hello dear Radiator users!

Some EAP protocols use outer identity only to locate a home RADIUS server
and thus users use anonymous outer identity (anonymous at domain.tld or just
@domain.tld as recommended by the RFC 4282)

Attached script copies the inner username to the Access-Accept User-Name field so
a NAS (Access Point) can provide accounting information with correct (inner)
User-Name.

This, new version of the script also handles the RFC 4282 @domain.tld outer
identities correctly.

Example configuration:

<Handler Realm=domain.tld>
        RewriteUsername s/^([^@]+).*/$1/
        AuthBy static_users
        PostProcessingHook file:"/home/radius/etc/eap_acct_username.pl"
</Handler>
