Troubleshooting the Microsoft SharePoint integration

This chapter provides an overview over complications administrators might experience when enabling the integration of the Signavio Collaboration Hub with Microsoft SharePoint.

Microsoft SharePoint 2010/2016 Installation errors

Error: The commands to install, deploy, uninstall or remove the SharePoint solution do not work.

Solution: Make sure the Windows Service SharePoint Administration is up and running. By default, the startup options of this service are set to manual.

Error: Invalid authentication token/cannot resolve host

Solution: If your SharePoint system setup allows you to make changes to the web.config file of your SharePoint application (the default location is C:\inetpub\wwwroot\wss\VirtualDirectories\80), please make your that the useDefaultCredentials flag is set to true. By using this configuration the SignavioViewer can make use of the system’s proxy configuration that Internet Explorer is using as well.

On the SharePoint server, go to Configuration - SharePoint - SafeControls - SafeControl and ensure the entry looks as follows:

<SafeControl Assembly="SignavioViewer2013" Version= Culture=neutral PublicKeyToken="e6770998a80d4130"
 Namespace="SignavioViewer2013.SignavioVisualWebPart" TypeName="*" Safe="True" />

Furthermore, check the following entry: Configuration - system.web - trust:

<trust level="Full" originUrl="" />

Sharepoint app cannot perform requests to the Signavio server

Error: When the SharePoint app tries to authenticate against the connected workspace on the Signavio server, it displays the error “unable to connect to the remote server”.

Solution: If you configured the IIS server SharePoint is running on using Integrated Security without anonymous access and the impersonation feature is turned on, the Signavio SharePoint App might not be able to perform requests to any server outside the local network.

The suggested solution is to disable impersonation and to allow the account running the SharePoint application pool internet access.

The following blog post describes the problem in-depth:

Sharepoint security token issue

Error: An operation failed because the following certificate has validation errors

Subject Name: CN=SharePoint Security Token Service,
OU=SharePoint, O=Microsoft,
C=US Issuer Name: CN=SharePoint Root Authority,
OU=SharePoint, O=Microsoft,
C=US Thumbprint: 50928B849FD8AFD29A6562B6E19F45E93397F6CC

Solution: The local root certificate might have been deleted. Make sure to set the certificate in place.

The following blog post describes the problem in-depth:>

The read access management dialog does not load users and user groups

Error: The Manage users - Read access dialog reports that the SharePoint Connector is not available.

Solution: Activate the loading of mixed content in your Internet Explorer configuration settings under Internet options - Security - Custom level (Internet zone).

The user’s Collaboration Hub remains empty

Error: The user’s Collaboration Hub remains empty

Solution: Probably, you haven’t granted access to any published diagram, yet. Read about how to grant read access at Manage read access rights.

SharePoint displays the Signavio login page, although the authentication mechanism was configured correctly

Error: When opening the page that contains the Web Part, the Signavio login page is displayed instead of Collaboration Hub.

Solution: In your browser, please check if you are logged in as Signavio modeler or workspace administrator. If so, log out and reload the SharePoint page.

Authentication Certificate

If you use the Signavio SharePoint App with the software-as-a-service version of Signavio Process Manager, please update the authentication certificate by December 15, 2016.
