Atlassian SharePoint Connector

Atlassian SharePoint Connector combines free-form content creation and collaboration with the document management and workflow strengths of SharePoint. Blend enterprise documents and lists with rich Confluence content, all on a single SharePoint page. It has support for Web Part Connections allows users to browse through an entire Confluence space - pages and blog posts - without leaving SharePoint. Share and instantly edit SharePoint documents within lists embedded in Confluence. You can seamlessly navigate between SharePoint and Confluence since users are shared via Microsoft Active Directory. With a single username and password for both applications, sign into one application and you're signed into both.
