Hi,
thanks for that blog post, the workaround works!
Unfortantly there exist only a unsupported method to do this. I have opend an ms connect issue, perhaps ms will work on a supported system setting for this in further releases.
In my opinion this feature would be a great benefit to integrate ie addons in MS CRM.
To all which shares this opinion, please vote for that issue in conncet:
