MSDN article, Enabling and Disabling Privileges in C++, provided the a code example to show how to enable or disable a privilege in an access token.
I quote the part in questioned:
tp.PrivilegeCount = 1;
tp.Privileges[0].Luid = luid;
if (bEnablePrivilege)
tp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;
else
tp.Privileges[0].Attributes = 0;
What is the meaning of zero value for Attributes member?
According to the documentation of TOKEN_PRIVILEGES structure, the attributes of a privilege can be a combination of the following values:
SE_PRIVILEGE_ENABLED(it is 0x00000002L inWinNT.h)SE_PRIVILEGE_ENABLED_BY_DEFAULT(it is 0x00000001L inWinNT.h)SE_PRIVILEGE_REMOVED(it is 0x00000004L inWinNT.h)SE_PRIVILEGE_USED_FOR_ACCESS(it is 0x80000000L inWinNT.h)
So, we don't see any valid constant with a value of zero. I guess, the zero is equal to SE_PRIVILEGE_REMOVED.
Anybody here could explain what the zero value really does?
