Embedding cannot always work

[polx]

It appears that the embedding function (which relies on the Drive API's embedLink property) cannot work in all cases.

People who have view access on the wiki page may be unauthorized to access the google drive.

There appears to be no way to be warned about this. In principle this would be ok if the user would be understanding that this problem can be solved by changing permissions at Google but thus far I only see a blank page.

While testing Google Apps Integration 2.5.2., I noticed that this indeed happens if a user, with only View right given at wiki level, goes to a page that has the Drive macro added and if they try to embed a file, they would be shown that access is denied for them.

They would also see a message like Unauthorized Error 401 if they go to a page where there is an embedded document already.
