Something doesn't work.

sites-enabled/default:
authorize {
         preprocess
         chap
         mschap
         suffix
         files
         sql
         logintime
         auth
}

radiusd.conf:
exec auth {
    program = "/usr/local/freeradius/run/Money %u %n %{NAS-Port}"
    wait = yes
    input_pairs = request
    shell_escape = yes
    output = no
    output_pairs = reply
}

If I check existence of spaces in User-Name in my program  
/usr/local/freeradius/run/Money all works.
If I insert

if (User-Name =~ /^\s/ || User-Name =~ /\s$/) {
		update reply {
			Reply-Message := "Remove spaces from User-Name"
		}
		reject
}

in section authorize{} in any place the user with spaces in User-Name  
successfully transits authorization.

This unlang-code doesn't work too

if (User-Name =~ /(.+)\s+$/i) {
		update request {
			User-Name := "%{1}"
		}
}

Where I was mistaken?
