Just as in the example I sent, the application will get permission denied during the time difference between the client and server clock. That is expected. What is not expected, in this variant, is that gss_init_sec_context() will succeed by itself once the client believes the TGT and service ticket to have expired. Apologies for any miscommunication on this point. There may be something in the calling code which refreshes the TGT in this situation. If so, then to fully understand the scenario, we need to know how the calling code decides when to refresh the TGT.
