YAY! I can answer something!
When you are using MAC RADIUS authentication the NAS (usually a wireless access
point) sends the machine's MAC address as the username, without any characters
like ":" or "." In it, so it is just a string. This line of code simply tells
PF that IF you are using RAD-MAC authentication, store the user-name attribute
as the MAC of the workstation.

Looking at packetfence.pm, I am curious. What does this mean
# in MAC Authentication the User-Name is the MAC address stripped of all
non-hex characters
my $mac = $RAD_REQUEST{'User-Name'};
Is \ a non-hex character?

Let's do the test.
Remove the perl module from the authenticate section.

Samba 3.5.11
The server is joined to the domain and I can run the ntlm_auth command and
login with either name format.
I commented out the ntlm_auth line in mschap, but that didn't change anything.
We need to enter the EAP tunnel before it will try to authenticate with mschap,
don't we?
rlm_perl runs packetfence.pm. Is that module having an issue with the backslash?
Were the servers you were connecting to Win 2008?

Tom,
The wierd thing is that I installed that same package on maybe 3 deployments,
and it worked at the first try for all of them. Is it possible that the samba
configuration is, for a weird reason, not right? Which version of samba you
installed?
Can you comment the ntlm_auth line in the mschap module, at least it should
fail saying RADIUS cannot find the proper username. Are the machines joined to
the domain? Can you also provide the samba configuration and your krb5.conf?
Also, what are the user rights for : /var/lib/samba/winbindd_privileged/
