When running a sync using the SyncEngine on a SharePoint 2013 environment an error occurs in the database. This will occur after adding a group with many users in the group and then running the sync.
The following error is visible in the [SyncEngine].[RunHistory] table in the AdditionalInfo column: “Invalid Request. The request XML is too complex”.
SharePoint 2013 uses CSOM calls that have a limitation when building the XML.
