Pass thru credentials to allow re-authentication

This is a backport of 4 fixes squashed into one because:

1. They need to all be merged together as they build on each
   other as problems were found in each change after it was
   merged on master.
2. The 3rd change won't pass Jenkins on it's own so it has
   to be squashed with the 4th and final change, so I'm just
   going to squash the entire topic branch together.

The change bugs fixed and cherry pick commit hashes are left
intact for each change.

Closes-Bug: #1241275
