* server_renew_identity -- Make sure that credentials are still valid, and
* enew them if they are not.
*
*
* This routine is called (with the current credentials) whenever a task
* is about to be attempted that requires valid credentials. For an ex-
* ample, see the cleanup code in "main()" above. A valid credential will
* nevertheless be considered invalid if it will expire within time_left
* seconds. This gives a margin of time between the validity check that
* occurs here and the actual use of the credential.
*
* Called from main() (but can be called from elsewhere).
