Restrictions
Important limitations and assumptions of the plugin:
- Installation of the plugin requires administrator Administrator permissions to run the deployment scripts from the SharePoint Management Shell (PowerShell).
- While a single installation of the plugin's .wsp file is necessary, a separate execution of the model deployment script is needed for each different Content Source that is published into StageR.

StagerBDCPlugin
The plugin is deployed as a .wsp file that gets deployed as a global farm solution. It implements the SharePoint BDC standard for custom connectors and gets executed from a SharePoint content source to extract the contents from STageR StageR and hand them to SharePoint for indexing.
Security Trimming
Security trimming is available within SharePoint 2013 itself. To make this work, a SecurityTrimmerPre interface must be created (see SharePoint 2013 Security Pre-Trimmer FAQ3.2).
The ISecurityTrimmerPre interface adds "claims" to the query prior to the security trimming; , so it executes “pre” (prior to) the security trimmer. With the exception of deny ACLs, the function of the ISecurityTrimmerPre module is to always add results to the result set, rather than to remove them. In this sense, it is the opposite of a security trimmer.

It is critical to understand that if the ISecurityTrimmerPre interface malfunctions, then you get no secure search results. (If it performed "classic" security trimming and malfunctioned, then you would get back extra unauthorized results.) On each search request, the Security Pre-Trimmer is invoked to enhance the search query with ACL information. This information is retrieved from an Aspire Group Expander (LDAP, Lotus Notes ...) |
