From the IAS Help file: RADIUS protocol
Remote Authentication Dial-In User Service (RADIUS) is an industry standard protocol described in RFC 2865, "Remote Authentication Dial-in User Service (RADIUS)," and RFC 2866, "RADIUS Accounting." RADIUS is used to provide authentication, authorization, and accounting services. A RADIUS client (typically a dial-up server, VPN server, or wireless access point) sends user credentials and connection parameter information in the form of a RADIUS message to a RADIUS server. The RADIUS server authenticates and authorizes the RADIUS client request, and sends back a RADIUS message response. RADIUS clients also send RADIUS accounting messages to RADIUS servers. Additionally, the RADIUS standards support the use of RADIUS proxies. A RADIUS proxy is a computer that forwards RADIUS messages between RADIUS-enabled computers. RADIUS messages are sent as User Datagram Protocol (UDP) messages. UDP port 1812 is used for RADIUS authentication messages and UDP port 1813 is used for RADIUS accounting messages. Some network access servers might use UDP port 1645 for RADIUS authentication messages and UDP port 1646 for RADIUS accounting messages. By default, IAS supports receiving RADIUS messages destined to both sets of UDP ports. For information about changing the UDP ports that are used by IAS, see To configure IAS port information. Only one RADIUS message is included in the UDP payload of a RADIUS packet. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Roseta Radfar Sent: Thursday, May 13, 2004 5:08 AM To: [EMAIL PROTECTED] Subject: [ActiveDir] Authentication port hi, I have a question , maybe it is off the topic but I will appricate any kind of help. even a reference. i want to know which port IAS uses for athentication. i want to write a program that does the some work before authentication and see if the user has permission based on our database then if he has then send it to windows for authentication. so i think i have to get the authentication request and then if i permit it goes for authentication in windows. it can be opposite if a user has been athenticated, i get the username and if i do not want him to be connected i will disconnect him. i want to know the port that i can get the request of authentication. that is some wherer to start with. any kind of reference is also appriciated. ..jjryãv .+-Šwè†Ûiÿü0Á-Š÷+ƒùšŠYb²Øm˜¸¬´P†Ûiÿü0Á-Š÷+ƒùb²×Úf.+-j·!Š÷¡¶Úÿ 0™¨¥j·!Š÷œ¢oÚrØyØãIšŠVœ¶+Þv*è®
