Domain Mapping, could it possible be causing problem with LinkedIn?

Hi,

This one is interesting. The basis of the problem is that when one of my client's employees adds a link to their website (which is hosted on my multi-site and domain mapped ) they get the 'screen shot' of the muslti-site top level site, not their domain, on LinkedIn.

I am of course scratching my head. Especially as I can't recreate the issue using my LinkedIn account.

The only thing I can think of that could be confusing LinkedIn (from my perspective) would be domain mapping.

But I have never seen this issue or heard of this issue from other clients (and I have quite a few on the same multi-site )

So I am really at a loss what to do.
