xCertReq failed with error

[PlagueHO]

Hi @svenvanrijen - thanks for reporting this. I actually ran across this issue last week on one my servers. So I was going to log this, but you beat me to it. Great work. Are you able to post your config for me (blank out any credentials or other sensitive info of course)?

Hi Daniel, no problem:

configuration Config            
{
  Import-DscResource -ModuleName xActiveDirectory, `
                                 xNetworking, `
                                 xPendingReboot, `
                                 xDHCPServer, `
                                 PSDesiredStateConfiguration, `

                                 xAdcsDeployment, `
                                 xCertificate

            RebootNodeIfNeeded = $true

    xComputer JoinDomain
    {
            Name          = $Node.NodeName
            DomainName    = $Node.DomainName
            Credential    = $domainCred
        }

    xCertReq SSLCert

            CARootName                = 'xxxxxxx-CA01-CA'

            CertificateTemplate       = 'WebServer'
            AutoRenew                 = $true
            Credential                = $domainCred
        }        
      }   
    }

$ConfigData = @{             
    AllNodes = @(             
        @{             
            Nodename = "*"             
            DomainName = "xxxxx.xxx"             
            RetryCount = 20              
            RetryIntervalSec = 30            
            PsDscAllowPlainTextPassword = $true            
        }

        @{             
            Nodename = "xxxx"
            Role = "DSC HTTPS Pull Server"             
            DomainName = "xxxxxxx.xxx"             
            RetryCount = 20              
            RetryIntervalSec = 30            
            PsDscAllowPlainTextPassword = $true
            PsDscAllowDomainUser = $true            
        }
   )             
}                   

It's quite a large config, so I just cut and paste the bits for the node that matters. If you need any more info or details, please let me know...

Kind regards,
Sven

Hi!
I've tried to troubleshoot this issue myself this, but unfortunately without any luck.
Guess it has something to do with creating and starting the Win32_Process within the PDT script... When I try this manually, I get an error regarding insufficient rights to start the process.

Anyway, I've got around it by changing my config to not use the $credential parameter and fixing an error in the xCertReq resource (https://github.com/PowerShell/xCertificate/pull/43/files). For now, my config runs smoothly, but the error mentioned above still exists.

xCertReq SSLCert
        {
            CARootName                = 'xxxxxxxxx-CA01-CA'
            CAServerFQDN              = 'xxxxx.xxxxx.xxxx'
            Subject                   = 'dsc01.xxxxx.xxxx'
            KeyLength                 = '1024'
            Exportable                = $true
            ProviderName              = '"Microsoft RSA SChannel Cryptographic Provider"'
            OID                       = '1.3.6.1.5.5.7.3.1'
            KeyUsage                  = '0xa0'
            CertificateTemplate       = 'WebServer'
            AutoRenew                 = $true
        } 

Kind regards,
Sven

Hi @svenvanrijen - thanks for the additional info! I'm definitely trying to get to this one. It is right up high on my list.

Hi
I have encountered this exact issue. As with @svenvanrijen removing the $credential, and modifying the xCertReq resource with Sven's code change works. My configuration is pretty much identical to the one Sven is attempting to apply. I'm doing this on Windows Server 2012R2 with all current patches applied.

[PlagueHO]

Hi @rikhepworth and @svenvanrijen - this does look like the solution to the problem. However the $credential is only required if the template requires an alternate credential to issue - so I don't think you'll need it mostly.

But because there is very little automated integration tests for this resource, I want to be certain that we're not making a breaking change. I've tried to implement some integration test for this resource (https://github.com/PowerShell/xCertificate/blob/dev/Tests/Integration/MSFT_xCertReq.Integration.Tests.ps1), so I'm just going to run these through on my CA's with the changes @svenvanrijen has made. I'm just doing this now and I'll get back to you ASAP.

Thanks again for your help and patience!

[PlagueHO]

@rikhepworth and @svenvanrijen - there is still some sort of issue going on when the $credential parameter is being passed. So even once @svenvanrijen has been merged I'll still keep this issue open till I can figure out what is causing this problem.
