Can i link my rel=publisher to a number of relevant microsites ?

[Antony_Towle]

We have linked our Google plus company profile to our main website and setup a rel=publisher authorship which appears and works fine in the SERPS as we regularly create Google plus posts about our industry and products.

We also gain some good traffic through some of our smaller product specific micro sites so i wanted to setup our publisher markup for these also as some of our posts are relevant to these products.

I setup the rel=publisher on one of these , but the Google snippet testing tool says that the rel publisher is unverified. Is this Google's way of saying i cannot use the same Google plus company profile across multiple sites

My question is:

Does Google not allow you to display the same Google plus rel publisher profile for multiple websites ? or is the there a problem with how i am marking up my micro sites ? has anybody tried this ?

You cannot, because the rel=publisher tag is a way of linking your website to your G+ page, and you can only link your page to a single website.
