LSF Version 7.3 - Platform LSF Configuration Reference

Figure 7: Default behavior (eauth executable provided with LSF)
The eauth executable uses corresponding processes eauth -c host_name (client) and eauth -s (server) to provide
a secure data exchange between LSF daemons on client and server hosts. The variable host_name refers to the host on
which eauth -s runs; that is, the host called by the command. For bsub, for example, the host_name is NULL, which
means the authentication data works for any host in the cluster.
Feature: External authentication
