Extend Web Applications to Different Zones for CRAWL Service and Search Support

The Agent for SharePoint does not support CRAWL services because the service does not use SiteMinder cookies. The SharePoint CRAWL service uses Windows authentication, and the Agent for SharePoint uses claims authentication. Because the SharePoint CRAWL service cannot respond to the authentication challenge the Agent for SharePoint makes, the Agent for SharePoint denies the request. When this denial occurs, the connection to the CRAWL service or the search times out.

follow these steps:

1. Extend the SharePoint web application with which you want to use the crawl service to a different zone.
2. Configure the extended web application (from Step 1) to use Integrated Windows (IWA or NTLM) authentication.
3. Configure the CRAWL service to use the URL of the extended SharePoint web application (from Step 1).

   Extending the web application to another zone provides protection of the web application with the Agent for SharePoint while supporting the CRAWL service and search functions.
