`krb5_post_recv_fn`

Hook function for inspecting or overriding KDC replies.

If code is non-zero, KDC communication failed and reply should be ignored. The hook function may return code or a different error code, or may synthesize a reply by setting new_reply_out and return successfully. The hook function should use `krb5_copy_data()` to construct the value for new_reply_out , to ensure that it can be freed correctly by the library.
