BYTE sidbuf[SECURITY_MAX_SID_SIZE];
PSID sid = (PSID)sidbuf;
if (GetAccountSidFromName(L"Sasha", sid, sizeof(sidbuf)))
{
PLSA_UNICODE_STRING userRights;
ULONG cnt;
LSA_HANDLE policy = GetPolicyHandle();

long ff=LsaNtStatusToWinError(status);

BOOL GetAccountSidFromName(LPCTSTR Account, PSID Sid, const DWORD SidSize)
{
SID_NAME_USE snu;
DWORD cbSid = SidSize, cchRD = 0;
LPTSTR rd = NULL;
BOOL succ = LookupAccountName(NULL, Account, Sid, &cbSid, rd, &cchRD, &snu);
if (!succ)

LSA_HANDLE GetPolicyHandle()
{
LSA_OBJECT_ATTRIBUTES ObjectAttributes;
USHORT SystemNameLength;
NTSTATUS ntsResult;
LSA_HANDLE lsahPolicyHandle;
// Object attributes are reserved, so initialize to zeros.
ZeroMemory(&ObjectAttributes, sizeof(ObjectAttributes));
// Get a handle to the Policy object.
ntsResult = LsaOpenPolicy(
NULL, //Name of the target system.
&ObjectAttributes, //Object attributes.
POLICY_ALL_ACCESS, //Desired access permissions.
&lsahPolicyHandle //Receives the policy handle.
);
return lsahPolicyHandle;
}
In my case sid is valid. GetPolicyHandle() is from MSDN.User name is Sasha as specified. Run on Visual Studio 2019 with admin rights.
I try find some solution at the Internet but found nothing. I have spended already 5 hours on it.
I have no idea how to fix it.Plaese help.
