Page Not Found: The original bucket to which this collection refers cannot be found

A domain created by the legacy Admin Console (port 90) contains the legacy Castor-Authorization header, which causes the Content UI to report "Page Not Found: The original bucket to which this collection refers cannot be found or has been replaced..."

The fix has two parts:

1. Remove the Castor-Authorization header (which removes Swarm access control and assumes your Swarm nodes are accessible only to trusted clients).
2. Ensure that the Caringo admin is a user in your Gateway IDSYS (idsys.json).

To remove the header, issue a COPY request directly to a Swarm node (the semicolon syntax to remove header values requires a curl version later than 7.29).

curl -v -u admin --post301 --location-trusted -XCOPY
    -H 'X-Owner-Meta: caringoadmin'
    -H "content-type:application/castorcontext"
    -H 'Castor-Authorization;'
    'http://SCSP_HOST/?domain=myolddomain&preserve&admin'
