Common Issues

Error: "The Account 'Joe User' Is Not Authorized to Perform the Requested Operation"

Cause: The account, used to create the SharePoint connector, doesn't have Site Collection access.

Fix: Update the account to have Site Collector access. How to Manage administrators for a site collection.

Behavior: SkySync isn't displaying all of my SharePoint library's content.

Cause: This can occur when accessing a SharePoint library that has a custom view (a view other than the default view), as it may impact SkySync's ability to retrieve the content or column data.

Fix: Please ensure the SharePoint library is configured to access content using the default view.

       Note: We hope to have this addressed in future versions of SkySync.

Authentication

Variable – Basic, Forms, NTLM, Kerberos, SSO

1. SSO – Okta, All with O365

2. On prem – Okta and ADFS

3. O365 - All SSO

Special Notes

Additional information regarding potential restrictions and nuances to the connector

1. Sites do not store files

2. URL of any site can be entered and used as a root

3. You cannot create sites through SkySync; it will create libraries.

4. If you create a folder within a document library using SkySync, it will be a folder container type.

5. Can only do versioning if versioning is enabled on the library.

6. Metadata is per library, not at the site level.

7. Impersonation of files only, not folders.

8. Managed metadata must be mapped by file if moving between 2 sharepoint instances (contact Portal Architects support for assistance with this procedure).

9. Date preservation only works with SharePoint if you are using author-preservation.

10. The transformation of URLs into SharePoint can sometimes increases the overall URL length which can cause either 400 or 414 URL failures (Spaces are the primary way this can happen).  We recommend the removal of spaces or shrink the URL length to resolve this errors.

Forms-Based Authentication

When Forms Based Authentication (FBA) is enabled for a SharePoint site, SkySync will always choose FBA over any other authentication method. When attempting an FBA connection, SkySync will make a call to the Authentication.asmx, passing the user credentials which must be from the FBA user list (it cannot be an AD user). Passing an incorrect user will return a password match error so it may not be clear that you have selected a user from the wrong list.

Is User Impersonation Supported?

SharePoint 2013 supports user impersonation through the SharePoint API but SharePoint 2007 and SharePoint 2010 do not.  The option is visible as they share the API but it is not available before 2013.
