Users Challenged Again when Accessing Office Document on SharePoint

Symptom:

Users who previously authenticated using SiteMinder are challenged for their credentials in any of the following situations:

• When they try to access office documents for which they are authorized on the SharePoint server.
• When they are working in an open document for which they are authorized on the SharePoint server.

This behavior usually occurs when using the following SiteMinder authentication schemes:

• Basic authentication
• Windows authentication

With other SiteMinder authentication schemes, the challenge can appear within the Microsoft Office document itself.

Solution:

The users are getting challenged because their session has expired. If you feel these challenges happen too often, you can change the session timeout intervals using either of the following:

• Administrative UI (r12.0 SP2)
• Policy Server User Interface (r6.x SP6)
