Wondering if anyone can help please. I have an on premise SharePoint 2013 environment which users used to access using: "DOMAIN\FirstName.LastName" however the organisation recently made a change and users are now authenticating using "[email protected]". Since this change users are being continuously prompted to login when accessing SharePoint via the browser or opening a document stored in SharePoint using office.

I have tried deleting the user profile service and completely recreating this however still no luck. Users are using a mix of IE and Chrome however I have checked all IE settings are set and also added the credentials to the credential managers, however still no luck.

Appreciate any help than can be provided.

  • Are you saying you switched from Windows Authentication to SAML or FBA? Or are users just using their UPN to login?

  • Users are still using their UPN, the default APN is what changed, this went from "domain.com" to "newdomain.com" and was bound to the users "domain\firstname.lastname"

If you changed domains you will need to use the Move-SPUser command to migrate the SharePoint users / permissions to the new domain.


  • Hi Josh, The domain has not changed, just the default APN, for instance it has changed from: "contoso.com" to "contosoengineering.com"

  • To give you a bit more information, when logging on to the site I am prompted for credentials in the format "[email protected]" however this fails, if I try to sign in as "contoso\joe.bloggs" then this works as expected and the site will authentication. However once I close the browser and login again I am asked to authenticate again.
