New Post: Add-CertificateTemplateAcl returned error when called from PowerShell remoting

Actually I had remoting configured using CredSSP already; otherwise, I got different error.
When I broke down the pipeline, it worked fine for Get-CertificateTemplate and Get-CertificateTemplateAcl.
The failure happened when calling Add-CertificateTemplateAcl.

I don't think that matters, but as a fyi: the remote server is Server 2012R2, the client is Windows Blue.
