Hi Steve,
To clarify the situation, I'd like to confirm the following information:
1. Regarding "I am having the same issue.", can you share us with the previous post you mentioned above? Is it http://community.office365.com/en-us/f/153/t/293525.aspx?
2. By saying "but the 'sync' client does not redirect to my companies page for authenticate", do you mean the issue only occur to OneDrive for Business for Mac client, while it work fine on iOS device?
3. Can you provide us with a screenshot of the page mentioned above for investigation?
To upload screenshots, click Use rich Formatting in this thread and select the Insert Image icon.
With more detailed information, we'll be able to understand the situation more clearer.
Moreover, here is an article about Types of supported authentication for the OneDrive for Business app for your reference.
Best regards,
Mills Fan
