Our Environment
we have deployed UAG 2010 SP3 in our environment for single sign on. we have published sharepoint 2010 and sharepoint 2007 through UAG. Client computers are running IE9 and Office 2010. 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.
previously when i opened any office document from sharepoint website published via UAG it office client prompted for authentication. i had "Disable scripting for portal applications turned on". once i turned it off there was no authentication prompt but then document only opens as read only.
i hope someone here will be able to help me here. thank you.
