Hello,

a user in #winehq came up with this problem, so I looked into it knowing the
app won't work at all due to low level hardware driver dependency.

Anyway it revealed at least a valid bug ;-)

--- snip ---

With the first call to GetTokenInformation( ... TokenGroups ... ) the app
queries the buffer size to hold result data -> lasterror =
ERROR_INSUFFICIENT_BUFFER.
The app allocates the required buffer and then calls GetTokenInformation() to
actually fetch the data.

Next, the app loops through sub authorities using GetSidSubAuthorityCount().
Normally it would look for DOMAIN_ALIAS_RID_ADMINS but the problem is the
GetLastError() call _before_ the actual comparison. If last error is != 0, the
app won't look at data returned by GetSidSubAuthorityCount().

The last successful call to GetTokenInformation() didn't reset last error at
all - it's still at ERROR_INSUFFICIENT_BUFFER:

--- snip dlls/advapi32/security.c ---
BOOL WINAPI
GetTokenInformation( HANDLE token, TOKEN_INFORMATION_CLASS tokeninfoclass,
             LPVOID tokeninfo, DWORD tokeninfolength, LPDWORD retlen )
{
...
    return set_ntstatus( NtQueryInformationToken( token, tokeninfoclass,
tokeninfo, tokeninfolength, retlen));
}
--- snip dlls/advapi32/security.c ---

--- snip dlls/advapi32/security.c ---
/* set last error code from NT status and get the proper boolean return value
*/
/* used for functions that are a simple wrapper around the corresponding ntdll
API */
static inline BOOL set_ntstatus( NTSTATUS status )
{
    if (status) SetLastError( RtlNtStatusToDosError( status ));
    return !status;
}
--- snip dlls/advapi32/security.c ---

This is probably an oversight. I don't know what Windows does but the app seems
to expect the last error being reset to zero (NTSTATUS success).
A conformance test should reveal this.
