Maybe just a typo in the email, but the -1 should be outside the
parentheses.

The indexing of the array goes from 0 to 5. But when you count the content
of the array then it goes from 1 to 6. So ulCount should be equal to 6.

However, you should get a match with just 5 attributes. The extra attribute
will just narrow the search. Is the object a private object? Then you also
need to C_Login() on your session before searching.

When searching for objects you usually just search using the CKA_CLASS and
CKA_ID. E.g. a private key with ID 1234.

This is the code that OpenDNSSEC uses when searching for objects.
