Hi,
Coverity found an unused variable in the krb5_child code. After reading the code again after a week it was written, I think we should do some changes for better readability.
Mostly, fail on error from get_tgt_times() and change the flow so the main branch (ie topmost indent) will be the success branch. It makes sense to shortcut on success the first time get_tgt_times() is called to check existing FAST ccache, but I think the second time, we expect success, otherwise the forked child failed.
