[Serusers] ser auth_raidus problem radius_authorize_sterman(

Hi there i have compiled the ser with auth_radius module. During my test in the log i can see that i get: res: -1 3(25958) radius_authorize_sterman(): Failure 3(25958) build_auth_hf(): 'WWW-Authenticate: Digest realm="209.250.135.8", nonce="4175e8b266ce69371b9d12a6b69c4ce3b541b313"^M i did followed everything in the FAQ and radius documentation .. But for some reason i cannot get through this problem. the radius client is the 0.4.5 but it does not help. Another issue is that i run radius -X and nothing ... nothing is showing on the log ??? when i run radtest as in document ion i do get the log ... in the radius .. If any one know where i did get stuck ??? please let me know Thanks
