By default SharePoint 2013
doesn’t provide option for sign in as a different user unlike we had option in
SharePoint 2010 ribbon.
Microsoft has removed this option
in SharePoint 2013 because of Caching problems, Documents opened in external
applications are saved with an unexpected user account and many more.
In order to enable this option we
need to follow below steps:
Step 1: Go to
C:\Program
Files\Common Files\Microsoft Shared\Web Server
Extensions\15\TEMPLATES\CONTROLTEMPLEATS.
Here we have a file
named welcome.ascx.
Step: 2
Open welcome.ascx in
Visual Studio or in Notepad and add the following code and save:
<SharePoint:MenuItemTemplate runat="server" ID="ID_LoginAsDifferentUser"
Text="<%$Resources:wss,personalactions_loginasdifferentuser%>"
Description="<%$Resources:wss,personalactions_loginasdifferentuserdescription%>"
MenuGroupId="100"
Sequence="100"
UseShortId="true"
/>
And it should be above the tag which has
ID_RequestAcess.
Step: 3
Refresh the site, and it's been enabled:
