This post describe the behavior when accessing SharePoint 2010 through Microsoft Unified Access Gateway (UAG). First you must have a site collection published through UAG. UAG have publishing templates for Microsoft Office SharePoint Server 2007 (MOSS) and SharePoint 2010. You have to select the corresponding template to get the best SharePoint experience. Furthermore we want able to access and edit Office files with Microsoft Office 2007 and higher. To fulfill this scenario the published SharePoint site must have selected the „Allow rich clients to bypass trunk authentication“ option.
Info
For MOSS there are exist explicit up- and download policies.
Now you are able to access SharePoint site collection. First try to access the SharePoint site collection through Internet Explorer. The next step is to open documents with Office applications like Word, Excel or PowerPoint. On a Computer with installed Office click one of the described file types. Your Computer will launch the application and try to impersonate you. To get this to work read the requirement section on this post.
Requirement
- Internet Explorer 6.x and higher
- SharePoint site collection have to be in „Local intranet“ or „Trusted sites“ zone (deactivate protected mode for corresponding zone)
Warning:
You can also disable „Protected mode“ on „Internet“ zone but that is a not recommended setting. If „Protected mode“ isn’t disabled you get repeated logon window and authentication will fail. Furthermore you will get errors for document check in and check out.
If all setting configured properly you have to authenticate once at the UAG and can use SharePoint without further authentication requests.
