EAP/TTLS Auth problem

[Steve Hopps]

I'm trying to use FreeRadius with OpenLDAP for authentication of some
Nanostation M2 access points, but have had no luck getting it to work.
When using rad_eap_test to experiment, I logged the following:

Found Auth-Type = PAP
# Executing group from file /etc/freeradius/sites-enabled/inner-tunnel
+- entering group PAP {...}
[pap] login attempt with password "-removed-"
[pap] Using CRYPT password "*"
[pap] Passwords don't match
++[pap] returns reject
Failed to authenticate the user.

Can anyone suggest what I'm doing wrong? The output for this section
is the same with rad_eap_test or the AP itself.
