I've just installed TFS2012 and am trying to create a new project in the default collection via Visual Studio 2012 but I keep getting this error message:
TF218027: The following reporting folder could not be created on the server that is running SQL Server Reporting Services: /TfsReports/DefaultCollection. The report server is located at: http://<servername>/Reports. The error is: The permissions granted to user '<domain>/grandmasterflush' are insufficient for performing this operation.. Verify that the path is correct and that you have sufficient permissions to create the folder on that server and then try again.
I've checked the permissions and my user is a member of the Project Collection Administrators and the Project Collection Administrators group has the 'Create new project' permission set to allow.
The only thing I think it might be is that the user that I created during installation for the Sharepoint access and reports viewing does not have permission to write to the reports folder, however if I select "Do not configure a SharePoint site at this time" then I still get the error messages. I can't find the reports folder to check the permissions either.
TFS is using an instance of SQL 2012 that was already on the machine when TFS was installed.
Can anyone see what I'm doing wrong please?
EDIT: If I try and create the project in VS when I'm logged in as administrator it lets me. I'm a bit confused by this as I would have thought that the server would run any attempts to create project folders as administrator, not as me.
RESOLUTION: Following on from Richard's answer, I browsed to http:///Reports/Pages/Folder.aspx and made viewed the "Security" option for 'TfsReports' and ensured that the AD group I had connected had the 'Team Foundation Content Manager' permission. This allowed me to start creating a project but didn't finish the wizard (see my comment to Richard's answer). It was only after I'd added the AD group with associated permissions to the 'Tfs2010OlapReportDS' and 'TFS2010ReportDS' objects in the folder that it fully worked.
I hope this post helps someone else and saves them the wasted hours I've just had!
