Description of problem:

When the Ceph dashboard is deployed with ssl and if the dashboard is behind a load-balancing proxy like HAProxy you might want to disable the redirection behaviour to prevent situations that make the dashboard unavailable due to the redirect mechanism enabled in the mgr.
According to the reference guide [1] this should be possible just setting the following config item:

 ceph config set mgr mgr/dashboard/standby_behaviour "error"
