WPA2 802.1X PEAPv0/EAP-MSCHAPv2

Greetings!
I am at a road block here. I know setting up WPA2 Enterprise
PEAPv0/EAP-MSCHAPv2 / 802.1X should be simple. It just isn't working!
Perhaps I am suffering from green screen syndrome :)
I have followed directions from: http://tldp.org/HOWTO/html_single/8021X-HOWTO/
Aside from mschap being in the <etcdir>/raddb/modules directory and
needing to enable mppe, the instructions are fairly straight forward.
The certificates are generated from our certificate store. I'm trying a
less complicated set up before moving on to OpenLDAP/Kerberos. During
the build process, I made sure that OpenSSL was available. LDD shows that
it is linked:
# ldd /usr/local/sbin/radiusd
/usr/local/sbin/radiusd:
libfreeradius-radius-2.1.8.so => /usr/local/lib/freeradius-2.1.8/libfreeradius-radius-2.1.8.so (0x280b3000)
libcrypt.so.2 => /lib/libcrypt.so.2 (0x280d5000)
libltdl.so.7 => /usr/local/lib/libltdl.so.7 (0x280ed000)
libssl.so.5 => /usr/local/lib/libssl.so.5 (0x280f7000)
libcrypto.so.5 => /usr/local/lib/libcrypto.so.5 (0x2813e000)
libpthread.so.1 => /usr/lib/libpthread.so.1 (0x282af000)
libc.so.5 => /lib/libc.so.5 (0x282d3000)
libz.so.2 => /lib/libz.so.2 (0x283ad000)
The client computers are laptops running OpenSUSE 11.2 x86_64.
Knetworkmanager is being used to configure the wireless security. the
settings are:
Security: WPA/WPA2 Enterprise
Authentication: Protected EAP (PEAP)
Anonymous Identity: <blank>
CA Certificate: /etc/ssl/certs/ca.pem
PEAP Version: Version 0
Inner Authentication: MSCHAPv2
Username: billgates
Password: 98502
The "users" file contains:
billgates User-Password := "98502"
What I get on the test laptop in wpa_supplicant:
Associated with 00:00:00:c0:ff:ee
CTRL-EVENT-EAP-STARTED EAP Authentication started
