Both TFS 2015 and Sharepoint 2013 Foundation are on-premise installations. They are on separate servers. Sharepoint is being configured post TFS installation - although I am not currently updating any existing projects.
Account being used to access the sharepoint site is a full admin on both sharepoint collection as well as TFS too.
TFS Extensions are installed, and configured on the Sharepoint server.
Can successfully create a new TFS 2015 project, and see it create the Sharepoint site - however upon accessing the Sharepoint portal site I see a number of TF30063: You are not authorized to access http://app-p-tfs01:8080/tfs errors.
I note that the collection is not listed on the url; I am looking to use the root web application of the sharepoint site as the root location.
Nothing appearing in Security event logs nor the TFS _oi audit.
Any pointers on where to look next?
