[Csdp] initial solution

I also have a question about the initial solution.

I have a new problem (probably containing typos) which returns 

<Iterations...>
Success: SDP is primal infeasible
Certificate of primal infeasibility: a'*y=-1.00000e+00,
||A'(y)-Z||=2.99456e-09
SDP failed.

In what way is the "initial solution" a solution if it is not feasible?
 What does it mean?

How can I use the certificate to debug the code?

Thanks,
Christopher Anand
