Delaying request 0 for 1 seconds Finished request 0 Going to the next request --- Walking the entire request list --- Waking up in 1 seconds... --- Walking the entire request list --- Waking up in 1 seconds... --- Walking the entire request list --- Sending Access-Reject of id 86 to 222.28.113.244:1174 ....... I have check the radiusd.conf and find the configuration like this: ....... # MODULE CONFIGURATION modules { pap { encryption_scheme = md5 } chap { authtype = CHAP } pam { pam_auth = radiusd } unix { cache = no cache_reload = 600 radwtmp = ${logdir}/radwtmp } eap { default_eap_type = md5 timer_expire = 60 md5 { } } mschap { authtype = MS-CHAP } } ...... # Authorization authorize { preprocess } .... # Authentication. authenticate { Auth-Type PAP { pap } } I don't whether I forget the PAP config and where to add the configure. Can anyone help me? thank you all so much~~
