[sharepoint-adfs](https://github.com/Azure/azure-quickstart-templates/tree/master/sharepoint-adfs)

### Issue Details
When configuring domain controller, following error message is displayed in the deployment process.

VM has reported a failure when processing extension 'ConfigureDCVM' (publisher 'Microsoft.Powershell' and type 'DSC'). Error message: 'DSC Configuration 'ConfigureDCVM' completed with error(s). Following are the first few: PowerShell DSC resource MSFT_WaitForADDomain failed to execute Set-TargetResource functionality with error message: No domain controller was found. (WFADD0010) PowerShell DSC resource MSFT_AdfsFarm failed to execute Set-TargetResource functionality with error message: Could not find a certificate with DNS Name 'adfs.contoso.local'. (FRMERR013)
Parameter name: CertificateDnsName The SendConfigurationApply function did not succeed. LCM failed to start desired state configuration manually.'. More information on troubleshooting is available at https://aka.ms/VMExtensionDSCWindowsTroubleshoot. (Code: VMExtensionProvisioningError)

Start with the sharepoint-adfs template linked in the issue and reproduce the deployment, using the Microsoft VM Extension DSC troubleshooting guidance. Trace ConfigureDCVM through the reported MSFT_WaitForADDomain and MSFT_AdfsFarm errors; done means the domain controller is found and the ADFS certificate is available so deployment completes successfully.
