Okay, thanks for the reply.
Is this a restriction for Web Clips or the entire Safari App?
If i can deploy the credentials for Safari, would it be possible to also deploy bookmarks and restrict the browser, so the user can only access whitelisted sites through it?
Then, I would also need a bookmark on the homescreen to the site (i dont think this is an issue...).
Regarding development... Unfortunately this site isn't hosted by us and i don't think our partner can or will change this just for us.
