Greetings. I have a list that has a People Picker column. When I add a new list item and start typing in a network ID into the People Picker control, the following message is displayed underneath the control: "Sorry, we're having trouble reaching the server". I fired up Fiddler and I can see the following requests being made:
1. POST /sites/hr/_api/contextinfo HTTP/1.1.
This has a 401 Unauthorized result
2. POST /sites/hr/_vti_bin/client.svc/ProcessQuery
This has a 404 Not Found result
So, it looks like authentication is failing on the SharePoint services (this probably explains why Search doesn't work either ;) ). I have the following authentication set in IIS on the site:
Anonymous -> Enabled
ASP.NET Impersonation -> Enabled
Basic Authentication -> Disabled
Digest Authentication -> Disabled
Forms Authentication -> Enabled
Windows Authentication -> Enabled
Also of note, this is a single-server VM environment containing SP 2013, SQL Server 2012, and is a DC. Thanks for any input!
