A good tool
Have been using this connector since very early on. Initially it was called eResults.
While the product was, at times frustrating, the vendor was always responsive, and would work with us to resolve any issues, whether they were a result of a bug, or through poor configuration.
Synchronises security so that SharePoint can perform security trimming.
Compared to the Microsoft Documentum Connector, the installation, and configuration of the BA solution, is a walk in the park.
