During LSF installation, the authentication method is set to external authentication (eauth), which offers the highest level of security.
For external authentication (the default), set LSF_AUTH=eauth
For authentication using the identd daemon, set LSF_AUTH=ident
For privileged port authentication, leave LSF_AUTH undefined
When the external authentication (eauth) feature is enabled, you can also configure LSF to authenticate daemons by defining the parameter LSF_AUTH_DAEMONS in lsf.conf.
All authentication methods supported by LSF depend on the security of the root account on all hosts in the cluster.
