Restrictions and limitations

For the supported Microsoft SharePoint server versions, consult the Technical Specification.

To use the AutoStore Add-on services connection method for Microsoft SharePoint 2016 and 2019, do the following:

1. Copy <Installation_folder>\Distributables\SharePoint\_nsi folder to C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\.

2. Copy <Installation_folder>\Distributables\SharePoint\NsiSPWS.dll to C:\inetpub\wwwroot\wss\VirtualDirectories\80\bin.

When the AutoStore Add-on services connection method is used, the component can upload files by using two different methods:

• Upload with buffering in the memory of the workflow server host machine. In this case, the size of the sent document is limited by available virtual memory on this computer.

• Streaming upload. This method is used automatically if anonymous access is allowed to the following file: C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\ISAPI\_nsi\NsiUploader.aspx on the SharePoint server host machine.

  In order to allow the anonymous access, in the IIS settings select a desired site, select the _vti_bin/_nsi folder, open Authentication, and set Enable status for Anonymous Authentication.

Use the most appropriate method for file uploading.

To work with this component, the user should have at least the 'Contribute' permission level for the specified folder, list, or document library.

To use impersonation, the user specified in the User name field should be a site collection administrator. With this option on, the documents and list items will be saved with the permissions of the impersonator.

If you use the Native Services connection method, then the component uses Client Side Object Model to access the server. These methods have the following special restrictions:

• On the General tab, the Server log file option is disabled.

• The component should be able to successfully transfer files up to 200 MB in size, but not more.

• The site list can be got only for the specified site collection.

If you use the AutoStore Add-on Services connection method, on the General tab, the Impersonate option is disabled.

The component supports only the integrated Windows authentication and Forms-based authentication methods.

The integrated Windows authentication methods rely on IIS authentication for SharePoint Web applications; the methods are NTLM or Kerberos (IIS Windows Authentication). IIS settings should be checked after the Web application is created: the Windows authentication method should be enabled.

The Forms-based authentication methods rely on IIS authentication for Claims-based SharePoint web applications. IIS settings should be checked after the web application is created: the Forms-based authentication method should be enabled.

When using multiple level metadata, the hierarchy will be displayed on the device panel as a list. However, the tree view will not be displayed. The full hierarchical path is displayed to make the selection of the right metadata easier.

For a proper operation of the component, Windows Identity Foundation (WIF) for .NET Framework 3.5 version should be installed on the machine, where workflow server is running.

The component is not able to retrieve and show more folders than the number specified in the List View Threshold field in the General settings of a web application on the SharePoint site. By default, this number is 5000.

Use of External Data fields has its additional number of restrictions that can be found in External Data field restrictions.

This component requires Token Vault to be installed and configured.
