Login Security Extension for the Extensible Provisioning Protocol (EPP)
                  draft-ietf-regext-login-security-00

Abstract

   The Extensible Provisioning Protocol (EPP) includes a client
   authentication scheme that is based on a user identifier and
   password.  The structure of the password field is defined by an XML
   Schema data type that specifies minimum and maximum password length
   values, but there are no other provisions for password management
   other than changing the password.  This document describes an EPP
   extension that allows longer passwords to be created and adds
   additional security features to the EPP login command and response.

1.  Introduction

   This document describes an Extensible Provisioning Protocol (EPP)
   extension for enhancing the security of the EPP login command in EPP
   RFC 5730.  The enhancements include supporting longer passwords (or
   passphrases) than the 16-character maximum and providing a list of
   security events in the login response.  The password (current and
   new) in EPP RFC 5730 can be overridden by the password included in
   the extension to extend past the 16-character maximum.  The security
