Publish to web to specific user: what happens when...

Hi to all,

we're planning to define an AD group where to insert the users who will have the right to publish.

However, I was wondering: what happens to the public web URL when a user is deleted (like isn't working anymore for the company) or (easier case) the user is removed from the group (like he has changed department)?

If the public URL stops to work, that might be an issue (you have to "re-publish" the dashboard with another user which has the right to do it)...so I was wondering if anyone has thought about this, and if it wouldn't be better to define a service user for the publish to web option.

Thank you
