can you help me?----PAP problem

[Lee Bobby]

hello,everyone,
I have written a client which send RADIUS packet to my freeradius 
server.There is problem about the PAP,like this:
......
modcall: group authorize returns ok for request 0
auth: No authenticate method (Auth-Type) configuration found for the 
request: Rejecting the user
auth: Failed to validate the user.
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 so much~~
