For multicluster environments that have different user accounts assigned to different
hosts, cross-cluster user account mapping allows you to submit a job from a local host and run the
job as a different user on a remote host.

Scope
Applicability
Details
Operating system
UNIX hosts
Windows hosts
A mix of UNIX and Windows hosts within one or more clusters
Not required for
Multiple clusters with a uniform user name space
Dependencies
UNIX and Windows user accounts must be valid on all hosts in the cluster and must have the
correct permissions to successfully run jobs.
If users at your site have different user names on UNIX and Windows hosts within a single
cluster, you must configure between-host user account mapping at the user level in
.lsfhosts.
Limitations
You cannot configure this feature at both the system-level and the user-level; LSF ignores
system-level mapping if user-level mapping is also defined in .lsfhosts.
If one or more clusters include both UNIX and Windows hosts, you must also configure UNIX and
Windows user account mapping.
If one or more clusters have different user accounts assigned to different hosts, you must also
configure between-host user account mapping for those clusters, and then configure cross-cluster
user account mapping at the system level only.
