Re: [Help-gnu-radius] Whitespace in the Username

First, inform radius that you allow whitespace to appear in usernames:

# raddb/config

options {
        username-chars " ";
        ...

(see
http://www.gnu.org/software/radius/manual/html_node/radius_21.html#SEC24)

Secondly, notice that delete_ws() cannot be directly used in
Rewrite-Function attribute. (see
http://www.gnu.org/software/radius/manual/html_node/radius_207.html#SEC308
for the description of the attribute and its requirements). What you
need to do is add an interface to it, e.g.:

integer
my_rewrite()
{
        %[User-Name] = delete_ws(%[User-Name]);
        return 0;
}

(it is a good idea to place this definition in the same file where
delete_ws() is declared) and then use this function as the value of
Rewrite-Function attribute:

 DEFAULT Group = "dynamicgrp", Strip-User-Name = No
         Hint = "single",
         Simultaneous-Use = 1,
         Service-Type = Framed-User,
         Framed-Protocol = PPP,
         Rewrite-Function = "my_rewrite"

 DEFAULT Group = "multi", Strip-User-Name = No
         Hint = "multi",
         Simultaneous-Use = 2,
         Service-Type = Framed-User,
         Framed-Protocol = PPP,
         Rewrite-Function = "my_rewrite"
