FreeRADIUS+rlm_chap+странная проблема

После перехода с RedHat на OpenSuse 10.1 возникла странная проблема с chap аутентификацией. Для тестирования данные берутся из файла /etc/raddb/users:

testuser Auth-Type:=CHAP,User-Password=="secret"

На сервер еще настроен pptpd с radius плагином

C клиента подключаемся по pptp

pptp 192.168.10.253 remotename 192.168.10.253  name testuser noauth

/etc/ppp/chap-secrets:
testuser 192.168.10.253 secret *

На сервере запущен radiusd -X

Получаем (вывод не полный):
