BW Report iview and SSO w/Logon Tickets

I have some BW Report iviews configured which work great for me however I can't get them to work for any other endusers. I have administrator access and they do not. The error they get is;

Unable to lookup System 'aBWP100'. Please check the system object and the alias..

aBWP100 is our BW server name. I searched for OSS notes but didn't find anything. Any suggestions?
