How to rename ID Field in a Sharepoint List

Requirement: Rename ID field in a SharePoint list! We had a list with ID column added to the view to provide unique auto number feature. User wants to rename ID field to “Change Request Number” as it sounds more appropriate.

rename ID field in SharePoint

Solution: Hidden columns such as “ID”, “Workflow Status” are not providing Edit features directly from SharePoint web UI and they don’t even appear on SharePoint list settings page.

So, use this simple trick to rename any hidden column such as ID:
Go to List settings page  and Pick any column such as “Title”. You’ll get Edit Column page.
In the URL, Change the Field parameter from “Title” to “ID” and Hit Enter. E.g.

Sharepoint 2013 Log in as a different user missing, a simple workaround

In their infinite wisdom, Microsoft decided to remove the ‘sign in as another user‘ option from the UI. For consultants and developers who need to test their solutions in an ongoing manner, user accounts need to be switched in order to test the myriad of permission issues sometimes experienced by users.

After some extensive research I have found a solution:

Simply append the following behind your URL – /_layouts/closeConnection.aspx?loginasanotheruser=true

e.g http://yoursite/_layouts/closeConnection.aspx?loginasanotheruser=true
