DLP Servers not resolving server names

=== Applies To ===

  • Linux OS

=== Problem Summary ===
After installing SharePoint .wsp file on the SharePoint server, DLP Discover server shows the below error when attempting to scan SharePoint:

ERROR: Failed to read <SharePoint_site_URL>; error: Failed to initialize scan for content root <SharePoint_site_URL>. Reason: Unable to resolve <SharePoint_site_URL>. Verify if the host name is valid.

=== Solution ===
Update resolve.conf
Steps for Linux Enforce server and all detection servers:

  1. SSH to Enforce/Detection server(s), login as appuser and update resolv.conf:
    sudo vi /etc/resolv.conf
  2. Verify nameserver entries point to valid DNS servers. Add multiple lines for more DNS servers
    Example:
    nameserver 10.10.12.90
    nameserver 10.10.55.20
  3. Add in a search line. This will allow you to use short names instead of FQDNs within DLP.
    Example:
    search mycompany.com
  4. Save the file and exit
    :w
    :q
  5. Restart network services
    sudo service network restart
