Environment:
SharePoint 2013 (recently upgraded to SP1)
- 4 servers: App, SQL, WFE and Search
Office Web Apps 2013 (recently upgraded to SP1)
- 1 server
So we installed SP1 on SharePoint, installed SP1 on Office Web Apps, switched to Kerberos authentication and then replaced UAG with ADFS. Lots of changes in a short amount of time. Since the upgrade, when extranet users authenticate through ADFS, they are prompted for credentials every time they open an Office doc in <strike>OWA</strike> MS Office applications like Excel and Word. Intranet users don't get this prompt but most of our company works off the extranet site. We're using claims-based authentication in SharePoint and didn't have this problem with UAG.
Anyone seen this before?
