Thanks for the tips.  I followed everything, PAP worked fine, but I still
had problems with EAP even with using the certificates from the Radius
disto.  The part that didn't make a lot of sense to me was it would go thru
all the process, and MSCHAP showed success:

[mschap] Creating challenge hash with username: test1
[mschap]        expand: --challenge=%{mschap:Challenge:-00} ->
[mschap]        expand: --nt-response=%{mschap:NT-Response:-00} ->
Exec-Program output: NT_KEY: D17434B7303CD6FA2ABE17CDB536D69D
Exec-Program-Wait: plaintext: NT_KEY: D17434B7303CD6FA2ABE17CDB536D69D
Exec-Program: returned: 0
[mschap] adding MS-CHAPv2 MPPE keys
++[mschap] returns ok
MSCHAP Success

But after that was [peap] Got tunneled reply code 11.  Some searches on
google indicated that I might be facing a Samba bug.  After upddating to the
latest release 3.5.6 and adding winbind:forcesamlogon to the smb.conf file
it started working.

Now I am off to adding LDAP for group membership and configure for dynamic
vlans and acls.
