SIGN IN As a Different User in SharePoint 2013 Server

In SharePoint Server 2013, noticed  that the Sign in as Different User menu option is missing.
This was a great tool for developers and IT pro who wanted to test their solutions or customizations. Missing this option in the new version of SharePoint.

May be There can be multiple reasons like

1. Caching Problems
2. Documents opened in external applications are saved with an unexpected user account .
3. Page content shows information from the previous user due to cached information.
4. Session variables contain information from previous user as the cookies are not cleared.

The Sign in as Different User functionality is not meant to be used as a security feature! This feature allows users which have more than one AD account to quickly login with a different account to SharePoint - but it does not guarantee that no artefacts from the previous user remain!

If you have to guarantee that one user cannot see data from a different user you have to logoff/logon in Windows. Don't use the Sign in as a different user.

To work around this issue, use one of the following methods. 

Start Windows Internet Explorer by using the Run as different user option, and then go to the SharePoint site
Access the SharePoint site by using the following URL: http://<site url>/_layouts/closeConnection.aspx?loginasanotheruser=true 

Locate and then open the following file in a text editor:
 C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\15\TEMPLATE\CONTROLTEMPLATES\Welcome.ascx (use always a copy).

Add the following element before the existing "ID_RequestAccess" element:

<SharePoint:MenuItemTemplate runat="server" ID="ID_LoginAsDifferentUser" 
MenuGroupId="100" Sequence="100" UseShortId="true" /> 

Save the file.

Another way is to use a runas.exe shortcut to launch browser as another user. Less convenient, but more reliable in the long run.

Or the last way is to create a JavaScript bookmarklet using your URL plus some client object model who can be checked here: http://corypeters.net/2012/10/sharepoint-2013-sign-in-as-another-user/

  1. i think we can do the same thing the other way..
    start-- admin tools -- local security policy -- security options -- in that interactive logons, number of previous logons it will be 10 we need to change that to 0.
