Do you want to be able to use both names (vrotest.test.dom and orchestrator-test.test.dom), or only the alias name will be enough?
If the latter, I'd suggest to try to change the host name in vRO Control Center > Manage > Host Settings.
If the former - I'm not sure, I think there were some issues with communication flow with configured authentication provider if the address being used doesn't match the value configured in host settings page.
thanks for your fast response. Its a demand of the Active Directory Team to use a specific host name so unfortunately that cannot be changed.
In Productive Environment that host name is a ten digit combination of letters and number...
Because I am very oblivious, I prefer to use an alias instead of host name. I the Prod-Environment with vRO 7.5 that works very well.
So if I get you right, there is no point to configure to use hostname and alias?
many thanks and kind regards,
