radius not recieving username from cisco

[Athiqur Rahman]

Hi,

I have an as5300 IOS Version 12.2 and FreeRADIUS Version 2.1.8

When I open ppp connection to from windows xp laptop to my as5300 it is 
not sending the login credentials to the FreeRadius. FeeRadius says the 
username attribute was not found

below is the snippet of debug output
