[Coin-ipopt] lagrange multipliers

I am trying to solve the Goddard rocket problem with and without the AMPL interface. 

Is AMPL only responsible for solving the matrices, or does this also give the values for the Lagrange multipliers to IPOPT? 

Is the computing of the Lagrange multipliers through IPOPT good approximatied? or could it also lead to errors?
