There was no option to edit user profiles. Under Manage User Profiles. The result of users would be listed, but the menu dropdown to edit was not visible. Profile properties also had the same issue. Properties did not have a menu option to edit.
Solution: Add Central Admin to IE 11 compatibility view settings in the browser. Seems IE 11 is not compatible with SharePoint 2013 Central Admin.
To add the option to sign in as a diff user in 2013 follow these steps:
Locate the file \15\TEMPLATE\CONTROLTEMPLATES\Welcome.ascx
Add the following element before the existing element with the id of “ID_RequestAccess”:
<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.
Do on each WFE. careful updating hive files. any updates will overwrite your changes…
