Hi Alan,

And thanks for your reply.
My radius is on private LAN, so no risk.

      Yes.  For security.  Otherwise, any user could do an SQL injection attack.

      See raddb/mods-config/sql/main/mysql/queries.conf
      Uncomment, and edit the "safe_characters" string.
      And then watch people pwn your database.  Because there's no separate list of safe characters for SELECT versus INSERT.
      We're working on fixing this for v4.
      i.e. you're better off *not* putting the "+" into the DB.
