RDM & Powershell: Switching from datasource SQL server to DVLS

Hello,

Up till now, we're using an (on premise) Microsoft SQL server as backend for our Remote Destkop Manager (RDM) with using a local SQL server account.

Setting up is done like this:

# Setup a new datasource
$datasource = New-RDMDataSource -Name $rdm_datasource_name -SQLServer -Server $rdm_datasource_server -Database $rdm_datasource_database_name -Username $rdm_datasource_username -Password $rdm_datasource_secure_password
Set-RDMDataSource $datasource

# Setup default RDM datasources
Set-RDMCurrentDataSource -DataSource $datasource -Username $rdm_datasource_username -Password $rdm_datasource_secure_password

We can then can then retrieve sessions, like Get-RDMSession

Now, we're in the transition of switching to DVLS. Now I setup the datasource like this. For getting started, I tried with the DVLS local admin account (created upon setup of DVLS)

# Setup a new datasource (witht a different name then SQL server example from above)
$datasource = New-RDMDataSource -Name $rdm_datasource_name -DVLS -Server $rdm_datasource_server -Username $rdm_datasource_username -Password $rdm_datasource_secure_password
Set-RDMDataSource $datasource

# Setup default RDM datasources

Set-RDMCurrentDataSource -DataSource $datasource -Username $rdm_datasource_username -Password $rdm_datasource_secure_password

However, I cannot retrieve any sessions:
Get-RDMSession : Connection not found.

But datasource looks fine?

Get-RDMDataSource

Can anyone help pointing out this issue? thanks!
