Installing p12 certificate under Local System Account (Windows Server 2008)

I'm running TeamCity 5.1 on a Windows 2008 server. TeamCity runs under the Local System Account (LSA) per default.

I checkout a Visual Studio 2010 project that contain a p12 certificat. I build the project using the solution file (sln).

The build fails with the following error message:

C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets(1970, 9): error MSB3326: Cannot import the following key file: . The key file may be password protected. To correct this, try to import the certificate again or import the certificate manually into the current user’s personal certificate store.
C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets(1970, 9): error MSB3321: Importing key file "cert.p12" was canceled.

So I use the Certificates.msc to import the certificate into the Personal section of Certificates - Service (TeamCity Build Agent Service) on Local Computer under TCBuildAgent\Personal\Certificates.


That does not resolve the issue.


So (in irritated frenzy) I install the certificates in every store i can find, but nothing (positive) happens.

I then try installing the certificate under LSA using the tool PsExec, but nothing is resolved.


So what am I doing wrong? Obviously I cannot brute force solve this one Any help is much appreciated!
