Introduction

You might have noticed that the UNC SharePoint Collaborative System frequently prompts you to login. It prompts you to login when you first open the site and prompts you to login again every time you open a Microsoft Office document. This can be a significant inconvenience, especially when using Shared Document libraries.

Fortunately, there is a solution that allows you to access SharePoint without ever having to login. This solution is referred to as single sign-on.

To use single sign-on, you must meet the following conditions:

1. Your computer must be a member of the AD.UNC.EDU or DEPTS.UNC.EDU domain. To determine your computer’s domain membership, seeWhat is my computer’s domain membership?

2. You must login to your computer using your domain account. You cannot login using a local account.

3. You must be granted permissions in SharePoint using the same account you use to login to your computer.

Instructions

The procedure to enable single sign-on to SharePoint depends on the browser you are using. Choose the instructions below that match your browser:
