PowerShell remoting with vRO normally gives you a 'local only' session which means resources or operations which require a 'second hop' to another machine this will not be permitted. We have found that you need to enable CredSSP authentication on the PS host, then you can perform a pseudo 'su' as in Linux by doing this
vRO creates remote session on PS Host (where CredSSP is enabled)
Execute PS script on the host to do
create additional PS session to the PS host using domain/admin credentials
-- Inner session
Execute privileged commands in inner session (2nd hop is allowed here - but be aware that remote targets (e.g., DC) will need to have CredSSP enabled also)
close inner session
Exit script
It works pretty well & we have built a number of PowerShell integrations like this before
DNS
DHCP reservation
Azure provisioning using Azure RM
Software installation
probably more I've forgotten
