Because this is configured for individual clusters, not globally, different cluster pairs can use different systems of authentication. You use a different eauth program for each different authentication mechanism.
Contact Platform Professional Services for more information about the eauth programs that Platform distributes to allow LSF to work with different security mechanisms. If you already have an eauth that works with LSF for daemon authentication within the cluster, use a copy of it.
If different clusters use different methods of authentication, set up multiple eauth programs.
In this example, Cluster1 and Cluster2 use Kerberos authentication with each other, but not with Cluster3. It does not matter how Cluster3 is configured, because there is no extra authentication unless the configurations of both clusters agree.

LSF_SERVERDIR in Cluster1 includes an eauth executable named eauth.KRB.
