title: SDL Tridion 2011 UI - Server Errors when loading
body: <p>When loading the new Tridion UI page the following errors appear in the message center.</p>
  
  <p>/WebUI/Models/SiteEdit/Services/Services.svc/GetSiteEditItemConfiguration failed to execute.</p>
  
  <p>/WebUI/Models/TCM54/Services/General.svc/GetTridionWebSchema failed to execute.</p>
  
  <p>/WebUI/Models/TCM54/Services/Blueprinting.svc/LoadBlueprintInfo failed to execute.</p>
  
  <p>These are the full errors.</p>
  
  <p>The client has a 'Single Sign On' system provided by 'Siteminder'. We need to login to show popups and for the bootstrap.apsx to load. Could this be causing the above errors. If so how do I integrate Tridion UI with Single Sign On?</p>
