Regular expression - Trying to rewrite User-Name

[Damian Porter]

 I have bee struggling with problem for a few days now.

I use Centos 4.3 and freeradius 1.0.1. I am trying to rewrite a username to
include dashes. see my statement below in the rewrite section.

           searchfor =
"([a-z0-9]{2})([a-z0-9]{2})([a-z0-9]{2})([a-z0-9]{2})([a-z0-9]{2})([a-z0-9]{2})
            replacewith = "%{1}-%{2}-%{3}-%{4}-%{5}-%{6}"

this is the output that i am getting in my radius.log file.

PS i have even gone as far as downloading regular expression programs to
check my code. If anybody has any suggestions or has encounted this problem
before let me know.
