Message:

Related to ticket 554: handle the case where server rejects Authorization because of incorrect nonce but fails to set stale parameter to true. In this case we will retry the authentication as long as the nonce in the challenge is different than current nonce. This seems to have fixed ticket 554 too (to be confirmed)
