I can try adding a suffix on the hostname field in the VCSA's DCUI, (to make it an FQDN) but it doesn't take.
It lets me edit the field.. but by escaping that area of the menu and saving settings.. the hostname field reverts to be null/void.
If I negate the suffix, and just go 'vcenter' instead of 'vcenter.local'.. Then it holds after a management network restart.
Where does one configure the VCSA 6.0 ? I.e. the SSO settings that I had access to in VCSA 5.5.. in 6.0 it is now ?
I'm convinced this is an SSO thing....
