Troubleshooting PerformancePoint Dashboard Designer Data Connectivity to SharePoint Lists

Send to Kindle

Here is a quick note with regards to PowerPivot Dashboard Designer connecting to SharePoint lists utilising Per-user identity on the single server.  The screenshot above shows what I mean. I have told Dashboard designer to use a SharePoint list as a data source on a site called “http://myserver and chosen the “Per-user identity” to connect with the credentials of the currently logged in user, rather than a shared user or something configured in the secure store (which is essentially another shared user scenario). Per-user identity makes a lot of sense most of the time for SharePoint lists, because SharePoint already controls the permissions to this data. If you have granted users access to the site in question already, the other options are overkill – especially in a single server scenario where Kerberos doesn’t have to be dealt with.

But when you try this for the first time, a common complaint is to see an error message like the one below.

This error is likely caused by the Claims to Windows Token Service (C2WTS) not being started. In case you are not aware of how things work behind the scenes, once a user is authenticated to SharePoint, claims authentication is used for inter/intra farm authentication between SharePoint services. Even when classic authentication is used when a user hits a SharePoint site, SharePoint converts it to a claims identity when it talks to service applications. This is all done for you behind the scenes and is all fine and dandy when SharePoint is talking to other SharePoint components, but if the service application needs to talk to an external data source that does not support claims authentication – say a SQL Database – then the Claims to Windows Token Service is used to convert the claims back to a standard Windows token.

Now based on what I just said, you might expect that PerformancePoint should use claims authentication when connecting to a SharePoint list as a data source – after all, we are not leaving the confines of SharePoint and I just told you that claims authentication is used for inter/infra farm authentication between SharePoint services, but this is not the case. When PerformancePoint connects to a SharePoint list (and that connection is set to Per-user identity as above), it converts the users claim back to a Windows Token first.

Now the error above is quite common and well documented. The giveaway is when you see an event log ID 1137 and in the details of the log, the message: Monitoring Service was unable to retrieve a Windows identity for “MyDomain\User”.  Verify that the web application authentication provider in SharePoint Central Administration is the default windows Negotiate or Kerberos provider. This is a pretty strong indicator that the C2WTS has not been configured or is not started.

A lesser known issue is one I came across the other day. In this case, Claims to Windows Token Service was provisioned and started, and a local administrator on the box. In dashboard designer, here was the message:

In this error, you will see an eventlog ID 1101 and in the details of the log, something like this:

PerformancePoint Services could not connect to the specified data source. Verify that either the current user or Unattended Service Account has read permissions to the data source, depending on your security configuration. Also verify that all required connection information is provided and correct.

System.Net.WebException: The remote name could not be resolved: ‘myserver’

at Microsoft.PerformancePoint.Scorecards.DataSourceProviders.ListService.GetListCollection()
at Microsoft.PerformancePoint.Scorecards.DataSourceProviders.SpListDataSourceProvider.GetCubeNameInfos()

PerformancePoint Services error code 201.

This issue has a misleading message. It suggests that the server “myserver” name could not be resolved, which might have you thinking this was a name resolution issue which is not the true root cause. This one is primarily due to a misconfiguration – most likely through Active Directory Group policy messing with server settings. A better hint to the true cause of this issue can be found in the security event log (assuming you have set the server audit policy to audit failures of “privilege use” which is not enabled by default).

The event ID to look for is 4673, and the Task Category is called “Sensitive Privilege Use”. A failure will be logged for the user account running the claims to windows service:

Level:         Information
Keywords:      Audit Failure
User:          N/A
Computer:      myserver.mydomain.com
Description:
A privileged service was called.

Subject:
Security ID:        mydomain\sp_c2wts
Account Name:        sp_c2wts
Account Domain:        mydomain

Service Request Information:
Privileges:        SeTcbPrivilege

The key bit to the log above is the “Service Request Information” section. “SeTcbPrivilege” means “To Act as Part of the Operating System”

Now the root cause of this issue is clear. The claims to windows token service is missing the “Act as part of the operating system” right which is one of its key requirements. You can find this setting by opening local security policy, choosing Local Policies->User Rights  Assignment. Add the claims to windows token service user account into this right. If you cannot do so, then it is governed by an Active Directory policy and you will have to go and talk to your Active Directory admin to get it done.
