CrossForest PKI Connect-CertificationAuthority doesn't show displayname

[DanTheMan-NL]

Whenever I use Connect-CertificationAuthority -ComputerName {FQDN} to a CA in a different forest I receive an output without the displayname:

DisplayName                              ComputerName              IsAccessible ServiceStatus Type
-----------                              ------------              ------------ ------------- ----
                                         FQDN.example.com     True         Running       Enterprise Subordinate CA

Appearently the displayname is necessary for other commands to function properly because when I use this command output with another command I receive this error:

PS C:\windows\system32> Connect-CertificationAuthority -ComputerName {FQDN} | Get-PendingRequest
Get-AdcsDatabaseRow : Exception calling "GetDbReader" with "1" argument(s): "CCertView::OpenConnection: The RPC server is unavailable. 0x800706ba (WIN32: 1722 RPC_S_SERVER_UNAVAILABLE)"

I have not synced the CA objects with the forest where this management server is stationed and I'm not willing to do that because of security- and operational reasons.

In this issue I read this should be possible without syncing the objects: #26

Is there anyway to do this? I really want to use PSPKI on a management server in a different forest without having to sync the CA objects to this forest.

Can you show all properties from CA object? E.g. Connect-CertificationAuthority -ComputerName {FQDN} | format-list *. And confirm what version of PSPKI you are using.

This is the output I get. I only changed the real FQDN with {FQDN} the rest is the same with the blank output:

PS C:\windows\system32> Connect-CertificationAuthority -ComputerName {FQDN} | format-list *
