I am using CruiseControl.net for continous integration. I've created a repository for my project using VisualSvn server (uses Windows Authentication). Both the servers are hosted in the same system (Os-Microsoft Windows Server 2003 sp2).

When i force build the project using CruiseControl.net "Failed task(s): Svn: CheckForModifications" is shown as the message. When i checked the build report, it says as follows:

BUILD EXCEPTION 
Error Message: ThoughtWorks.CruiseControl.Core.CruiseControlException: Source control operation failed: svn: OPTIONS of 'https://sp-ci.sbsnetwork.local:8443/svn/IntranetPortal/Source': **Server certificate verification failed: issuer is not trusted** (https://sp-ci.sbsnetwork.local:8443).

My SourceControl node in the ccnet.config is as shown below:

<sourcecontrol type="svn">
  <executable>C:\Program Files\VisualSVN Server\bin\svn.exe</executable>
  <trunkUrl>
    check out url
  </trunkUrl>
  <workingDirectory>
    C:\ProjectWorkingDirectories\IntranetPortal\Source
  </workingDirectory>
  <username>
   ccnetadmin
  </username>
  <password>
     cruise
  </password>
</sourcecontrol>

Can any one suggest how to avoid this error?
