Common Problems with SharePoint Login
The most frequently reported SharePoint problems are related to login. Below are some common login problems and their possible solutions:
Problem: You attempt to login to sharepoint.uvm.edu, but the login prompt just keeps coming back. Eventually, you get an error stating "You are not authorized to view this page", "401.1", or "invalid username/password".
Solution 1: If you are attempting to login using Internet Explorer on a non-domain-joined computer you willl need to prefix your UVM NetID with "CAMPUS\". Thus, if your NetID is "jjimbob", you will need to login as "CAMPUS\jjimbob". Generally this is not necessary with other non-IE browsers such as Firefox 3.0 or Safari 3.x, but the "CAMPUS\" prefix will work with these browsers as well.
Solution 2: If you are attempting to login as a university guest (i.e. with a "GuestNet" account), you will need to prefix your GuesID with "GUEST\". Thus, if your GuestID is "jjimbob.hdoody", you will need to login as "GUEST\jjimbob.hdoody". This is a requirement for all browsers, not just Internet Explorer.
Problem: You login to SharePoint, and then open an MS Office document. When your Office application starts, you are requested to login again. This happens every time you open a new Office document.
Cause: Web browsers and Office applications do not share login credentials. Office is opening a new connection to SharePoint which requires a login that is separate from your browser login. On machines that are joined to the CAMPUS Active Directoy domain, "passthough" authenticaiton occurs (i.e. the credentials that you used when you logged on to your computer are passed to SharePoint by your browser or Office application automatically). On standalone Windows machines, Windows machines joined to other domains (such as the "COM" domain), or Macintosh computers, passthough authenticaiton is not possible.
Solution 1: Have your machine joined to the CAMPUS domain. See: https://sharepoint.uvm.edu/sites/ad/About/getting%20started.aspx for help getting started.
Solution 2: If your machine cannot be joined to the CAMPUS domain, you can minimize authentication prompts by leaving your Office application open after updating your document. In other words, close the document, but do not close the application. The Office application will continue to cache your credentials until you exit, so you will not have to re-enter your credentials each time you open a new document.
