2166 Extra builtin rewrite function: tolower(string)
----------------------------------------------------------------------
This builtin function can be used to add a level of case-insensitivity
to radius authentication. Our previous radius implementation didn't
care for case. We unfortunately we found out that we had a lot of
users depending on that :-( With this patch we can do:

raddb/rewrite
=============

integer
username_tolower()
{
        %[User-Name] = tolower(%[User-Name]);
        return 0;
}

radd/hints
==========

DEFAULT Rewrite-Function = "username_tolower" Fall-Through = "Yes"
