Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit X-RT-Original-Encoding: iso-8859-1 Content-Length: 687 It seems that AuthenticateProc() in athena\auth\leash\leashdll\lsh_pwd.c does not account for LPLSH_DLGINFO_EX structures with size of LSH_DLGINFO_EX_V2_SZ. The "An incorrect initialization data structure was provided." error dialog pops up. I have client code which calls Leash_kinit_dlg_ex with a dialog info structure of LSH_DLGINFO_EX_V2_SZ size. This client code was written against KFW 2.6 APIs.
