about_invalid_certificates SHORT DESCRIPTION When you connect to a server, VMware PowerCLI checks if the server certificate is valid. If the certificate is not trusted for this server, by default VMware PowerCLI fails to connect to thе server. LONG DESCRIPTION When you connect to a server, VMware PowerCLI checks if the server certificate is valid. If the certificate is not trusted for this server and use, by default VMware PowerCLI fails to connect to the server. Most VMware PowerCLI connect cmdlets support the Force parameter that forces the connection, even if there is an issue with the server certificate for this connection only. The InvalidCertificateAction parameter can change behavior based on the following options: - Fail (default) - the cmdlet will not establish a connection if the certificate is not valid. - Warn - the cmdlet will display a warning saying that the certificate is not valid, the reason why it is not considered valid, and then will print additional information about the certificate. - Prompt - if the server certificate is not trusted, the cmdlet will prompt you for a course of action before it continues. - Ignore - the cmdlet will establish the connection without taking into account that the certificate is invalid. On PowerShell Core, only the Fail and Ignore values are supported. If you want to check the current InvalidCertificateAction parameter, run the Get-PowerCLIConfiguration cmdlet. If you want to change the InvalidCertificateAction parameter, run Set-PowerCLIConfiguration -InvalidCertificateAction <new value>. If the InvalidCertificateAction parameter is set to Prompt, the the Invalid Certificate prompt appears. You can select one of the four options provided by the Invalid Certificate prompt: - Deny - Cancel the server connection. - Connect once - Establish the server connection and suppress further warnings for the current PowerShell session. - Add a permanent exception for the server_address/certificate pair - Persist the server certificate in the PowerCLI Trusted Certificate Store (PCTCS) for the current user and establish the server connection. - Add a permanent exception for all users - Persist the server/certificate pair both in the current user PowerCLI Trusted Certificate Store (PCTCS) and in All Users PCTCS, and establish the server connection. To set the default behavior of vSphere PowerCLI when no valid certificates are recognized, use the InvalidCertificateAction parameter of the Set-PowerCLIConfiguration cmdlet. POWERCLI TRUSTED CERTIFICATE STORE (PSTCS) The PowerCLI Trusted Certificate Store (SslCertificateExceptions.csv) is a CSV file with two columns: server_address and certificate_thumbprint. You can edit the (PSTCS) manually by using a text editor. There are two PSTCS files: - The current user PSTCS is located in the <PowerCLI user settings>/VMware/PowerCLI directory. - The All Users PSTCS is located in the <PowerCLI all user settings>/VMware/PowerCLI directory. For more information about the exact location depending on your operating system, see the Configuring VMware PowerCLI chapter in the VMware PowerCLI User's Guide. If you want to make changes to the All Users PSTCS, administrator/root privileges might be required. The local certificate storage file is purposely simple and you can easily import and export certificates from one machine to another or fill it with certificates automatically.
