From: Corinna Vinschen <corinna@vinschen.de>
Date: Mon, 30 Apr 2001 21:19:42 +0000
Subject:         * autoload.cc: Add LoadDLLinitfunc for secur32.dll.        
 Add LoadDLLfuncEx statements for AllocateLocallyUniqueId@4,        
 DuplicateTokenEx@24, LsaNtStatusToWinError@4,        
 LsaDeregisterLogonProcess@4, LsaFreeReturnBuffer@4,         LsaLogonUser@56,
 LsaLookupAuthenticationPackage@12,         LsaRegisterLogonProcess@12,       
  * environ.cc: Add extern declaration for `subauth_id'.        
 (subauth_id_init): New function for setting `subauth_id'.         (struct
 parse_thing): Add entry for `subauth_id'.         * fork.cc (fork_parent):
 Call `RevertToSelf' and         `ImpersonateLoggedOnUser' instead of
 `seteuid'.         * security.cc: Define global variable `subauth_id'.       
  (extract_nt_dom_user): New function.         (cygwin_logon_user): Call
 `extract_nt_dom_user' now.         (str2lsa): New static function.        
 (str2buf2lsa): Ditto.         (str2buf2uni): Ditto.         (subauth): Ditto.
         * security.h: Add prototype for `subauth'.         * spawn.cc
 (spawn_guts): Use cygheap->user.token only if impersonated.         Use
 `cygsid' type. Remove impersonation before allowing access to        
 workstation/desktop to everyone. Call `RevertToSelf' and        
 `ImpersonateLoggedOnUser' instead of `seteuid'.         * syscalls.cc
 (seteuid): Rearranged to allow using subauthentication         to retrieve
 user tokens when needed.
