"Sign in as Different User" menu option is missing in SharePoint Server 2013

Problem Description:

In Microsoft SharePoint Server 2013, you notice that the Sign in as Different User menu option is missing.

It’s really a shocked that this option has been completely removed from SharePoint Server 2013 but after debugging, I am able to find out workaround on this issue and I am pretty much sure that this will helps you to overcome this problem.

Workaround:

1.      Access the SharePoint site by using the following URL:

http://<site url>/_layouts/closeConnection.aspx?loginasanotheruser=true

2.      Manually add the Sign in as Different User menu option to the SharePoint site. To do this, follow these steps:

·         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 

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

                                                                                                   

<SharePoint:MenuItemTemplate runat="server" ID="ID_LoginAsDifferentUser"

Text="<%$Resources:wss,personalactions_loginasdifferentuser%>"

 Description="<%$Resources:wss,personalactions_loginasdifferentuserdescription%>"

 MenuGroupId="100"

 Sequence="100"

 UseShortId="true"

/>

Save the file.
