I'm working with a customer who is starting to use the toolkit to install certiicates. I looked at the code and I can re-create the problem with a pretty simple example below. Where-as Get-NcSercurityCertificate works (i.e; display existing cert's, the Install-SecurityCerticate fails indicating authentication error. My code sample and run time results are below. It demonstrates the credentials are good since the Get-NcSecurityCertificate works but the subsequent Install-NcSecurityCerrtificate fails with credential error. I am hoping this is easily re-created by anyone. Any ideas?
