Do you need content access account to crawl external data?
You will need to give the default content access account appropriate rights on the NORTHWND database and the Business Data Connectivity Service Application to allow it to crawl the external data. A lot of different errors can happen when crawling external data. The most common error you will receive is “Error while crawling LOB Contents”.
Is the BDC metadata model used for search?
The BDC metadata model includes several properties that are applicable to Search, many of which are required to support BCS indexing connector crawling. The following table describes the BDC model properties that are applicable to Search.
What are the two types of BCS permissions?
BCS has two types of permissions: Object permissions apply only to a specific External System, BDC Model, or External Content Type (ECT). Each ECT is a securable object.
Where does the BCS connect to the database?
The problem lays in the fact that the BCS connects to the database using the “NT AUTHORITYIUSR”. So execute the following steps. Enter under the page “General” the user name and login name “NT AUTHORITYIUSR”. Select the “OK” button to save your changes.
How are metadata store permissions applied in BCS?
Metadata Store permissions apply globally to the whole BCS store. That is, they apply to all BDC Models, external systems, ECTs, methods, and methods instances that are defined for that external data system. You can set permissions on the metadata store to determine who can edit items and set permissions for the store.
