Problem summary
**************************************************************** * USERS AFFECTED: * * End users of application using invoke procedure, running on * * MFP server 7.1 in session independent mode. * **************************************************************** * PROBLEM DESCRIPTION: * * If the application is sending two or more adapter invocation * * requests to server working in session independent mode, * * request can arrive to different nodes. * * As a result, the sever generates different challenges but is * * able to save only one challenge in the attribute store. The * * client might send a challenge answer for a challenge that * * was not saved in attribute store, which will cause * * authentication to fail, preventing the client from invoking * * the adapters. * * If the realm that failed is the device no provisioning * * realm, the error "received bad token from client" is logged * * by the server. * **************************************************************** * RECOMMENDATION: * * - * ****************************************************************
Problem conclusion
The server now allows the client to respond to no-provisioning device authentication challenges and authenticity challenges more than once. This allows the client and the server to "synchronize", and the challenges can be verified successfully.
