Title : How to create dynamic UPNs for invited ATTENDEEs Author(s) : D. Royer Filename : draft-royer-calsch-dynamic-upn-02.txt Pages : 12 Date : 2003-10-2 This is an extension to the [CAP] protocol and can be used within [iTIP] objects. A CU may wish to invite a UPN to an event where the UPN does not have a account on the CU's CS. This memo describes two methods to dynamically create UPNs in order for those UPNs to gain access to the 'Organizers' CS. This memo also includes a description of how to include an [OTP] challenge in an object directed to a CU. The CUA must compute the password in order to respond to the object. This challenge and its response can be sent in the clear as the values are computed using a secret that would not be known to anyone snooping the line.

Internet-Drafts are also available by anonymous FTP. Login with the username "anonymous" and a password of your e-mail address. After logging in, type "cd internet-drafts" and then "get draft-royer-calsch-dynamic-upn-02.txt".
Send a message to: mailserv@xxxxxxxxx In the body type: "FILE /internet-drafts/draft-royer-calsch-dynamic-upn-02.txt". NOTE: The mail server at ietf.org can return the document in MIME-encoded form by using the "mpack" utility. To use this feature, insert the command "ENCODING mime" before the "FILE" command. To decode the response(s), you will need "munpack" or a MIME-compliant mail reader. Different MIME-compliant mail readers exhibit different behavior, especially when dealing with "multipart" MIME messages (i.e. documents which have been split up into multiple messages), so check your local documentation on how to manipulate these messages. Below is the data which will enable a MIME compliant mail reader implementation to automatically retrieve the ASCII version of the Internet-Draft.
