  1. On every node of the Vantage system, use dig or nslookup to see the fully qualified DNS name of the directory server. If either utility returns multiple name registrations for a node, Digest-MD5 binding is probably not usable for LDAP authentication of database users, and you should use simple binding. See LDAP Binding Options.
  2. On the directory server, use a directory tool to find the DNS name in the directory.
  3. The names you obtain from the directory server and the Vantage nodes must match. Fix any mismatches on the database nodes.
