SharePoint crawler has insufficient permissions to crawl file shares

Symptoms

Consider the following scenario:

  • You create a file share on a server that's running Windows Server 2012 or a later version, and assign Read permissions to the SharePoint crawler (content access account).
  • For this file share, you set up a content source of the "File Shares" type through the SharePoint Search Service Application administration.
  • You start to crawl for content source of the "File Shares" type.
  • In the SharePoint Search Center, you run a search query for a file stored in the file share.

In this scenario, no search result is returned. Additionally, the following error message is generated in the crawl log:

The crawl account did not have sufficient privileges to access the security attributes of this file or folder. Ensure the crawl account has the 'Manage auditing and security log' privilege.

Resolution

To resolve this issue, assign the Manage Auditing And Security Log (SeSecurityPrivilege) privilege to the SharePoint content access account. To do so, follow these steps on the computer that hosts the file shares:

  1. Select Start > Run, type gpedit.msc, and then select OK.

  2. Navigate to the following location in the Local Group Policy Editor:

    Computer Configuration\Windows Settings\Security Settings\Local Policies\User Rights Assignment

  3. In the right pane, locate and right-click Manage auditing and security log, and then click Properties.

  4. Click the Add User or Group button in the Manage auditing and security log properties dialog box, and then add the crawl (content access) account that the SharePoint crawler uses.

  5. Click OK in the Manage auditing and security log properties dialog box.

    Note

    If you assign the Manage Auditing And Security Log permission by using a Group Policy Object (GPO), add the crawl account to the GPO.
