Thanks,

Well, I see code in security.c already uses pConvertSidToStringSidA var.  

But as I am lazy, I just am going to test if OpenProcessToken() succeeds 
and return from the test when it's not, thus avoiding further calls to 
ConvertSidToStringSid() and for example GetTokenInformation() which just 
fails with ERROR_CALL_NOT_IMPLEMENTED.

BTW, it fails on win9x with ERROR_NOT_ENOUGH_MEMORY when you pass 
TokenInformationLength = NULL.  Should this be tested outside the 
test_token_attr() or maybe shouldn't be at all?
