Hi! I am working around a CISCO ACS server to authorize users access in a web application. All is done and working but i would like now to support the password expiry procedure trought the MSChapV2 protocol. I edit a user on the server with the password expiration and when i connect with his credentials i receive the correct message from server: a AccessReject packet with in MS CHAP ERROR the string with the code 648 (Password expiry). I studied the RF2759 and it said that the change-password packet (id =7) should now be sent to change the old password with a new one. I am using jradius to communicate with the server but nothing i found on internet about it and the use of the change-password packet (examples or something other). Actually i found some sources (es. http://www.opensource.apple.com/source/eap8021x/eap8021x-100/EAP8021X.fproj/...) and i am tring to implement them converting the logic from C to java but it is going to be a very hard work. Does somebody know something (examples, sources, libraries) about the change-password packet sending? Thanks, bye Emanuel
