SPSecurity.AuthenticationMode property

Gets the user authentication mode for the SharePoint deployment.

Namespace:  Microsoft.SharePoint
Assembly:  Microsoft.SharePoint (in Microsoft.SharePoint.dll)

Syntax

'Declaration
Public Shared ReadOnly Property AuthenticationMode As AuthenticationMode
    Get
'Usage
Dim value As AuthenticationMode

value = SPSecurity.AuthenticationMode

public static AuthenticationMode AuthenticationMode { get; }

Property value

Type: System.Web.Configuration.AuthenticationMode
An AuthenticationMode that specifies whether the SharePoint deployment is using Windows, Microsoft ASP.NET 2.0 Forms-based, or custom authentication of users.

Remarks

This value is set with the <authentication> element in the web.config file. But if the calling code is inside a method passed to RunWithElevatedPrivileges, AuthenticationMode returns Windows, regardless of the setting in web.config.

To create a customized authentication system, set the <authentication> element in the web.config file to "None". Then add an authentication module and a membership and role provider.
