The (non-alphanumeric) characters that are valid in a user name
are defined by configuration directive `username-chars'. For
example (in file raddb/config):

option {
        username-chars "address@hidden&\/";
        ...

The at-sign is reserved for roaming user-names. It may appear in
username-chars, though.

When using such "extended" usernames in your plaintext user database,
be sure to quote them, e.g.:

"address@hidden" Auth-Type = Crypt-Local, ...

instead of

address@hidden Auth-Type = Crypt-Local, ...
