Enable or Disable NIS Authentication

Configure the FluidFS cluster to communicate with the NIS directory service. Adding multiple NIS servers ensures continued authentication of users in the event of a NIS server failure.

2. Click the File System tab.
3. In the File System view, select Client Accessibility.
4. Click the Directory Services tab.
5. Click Edit Settings in the NFS User Repository section. The Edit External User Database dialog box opens.
6. Enable or disable NIS:
   • To disable NIS, select the None checkbox.
   • To enable NIS, select the NIS checkbox.
7. In the NIS Domain Name field, type a NIS domain name.
8. In the NIS Servers text field, type the host name or IP address of a NIS server and click Add. Repeat this step for any additional NIS servers.

   • To increase the order of preference for a NIS server, select a NIS server and click Up.
   • To decrease the order of preference for a NIS server, select a NIS server and click Down.
