Symptoms:   One or more of the following symptoms might appear:

  • Users are unable to log on to Microsoft SharePoint Server 2010.

  • Logon fails.

  • People Picker fails to search or resolve and return an error message.

  • This event appears in the event log: Event ID: 8307 Description: An exception occurred in <Claim Provider Name> claim provider when calling <Method Name>: <Exception>.

    Important

    Some SharePoint Server 2010 components might require the claims provider and might not function correctly if it is disabled. For example, shared service applications might fail during a call because the security modules expect that the system claims were added by this provider.
