WSS 3.0 (Windows SharePoint service 3.0) websites use NTLM/Windows integrated authentication by default. Since V3.0, WSS supports Forms authentication mode provided by ASP. NET 2.0. However, many people find that the search function does not work after the WSS site is set to form verification.
This is because the wss3.0 search service only supports the NTLM verification model, so the search function does not work. However, we can expand existing applicationsProgramTo enable the search function.
The procedure is as follows:
1. Choose Management Center> application management.
2. Click "create or expand web application" and select "extend existing web application ".
3. Make sure that the Web application with form authentication is set in the Web application on the following page.
4. Select a random port or set a fixed port
5. Select NTLM
6. Select not to allow anonymous access
7. Select a region: custom
8. Click OK to create the extended application.
9. Make sure that the search crawling account can access this extended application.
10. In this way, the next search service can access the application to implement the search function.
You can test it on your own.
