we have deployed UAG 2010 SP3 in our environment for single sign on. we have published SharePoint 2013 through UAG. Client computers are running IE9 and Office 2013. the portal websites are added to trusted sites zone.
Issue
Single Sing On and other features of publishing SharePoint through UAG is working fine except when Microsoft document is opened with edit in Microsoft office option. the document always opens in read-only mode. when i go straight to SharePoint website i.e. bypassing UAG portal everything works fine as expected.
i surfed on the web for same problems unfortunately find many but without any resolution from Microsoft , please help its urgent to our environment
