In
a mixed UNIX/Windows cluster, LSF treats Windows user names (with
domain) and UNIX user names (no domain) as different users. The UNIX/Windows
user account mapping feature makes job submission and execution transparent
across operating systems by mapping Windows accounts to UNIX accounts.
With this feature enabled, LSF sends the user account name in the format
that is required by the operating system on the execution host.
Figure 1. Default behavior (feature not enabled)
Figure 2. With UNIX/Windows
user account mapping enabled
For mixed UNIX/Windows clusters, UNIX/Windows
user account mapping allows you to do the following:
Submit a job from a Windows host and run the job on a UNIX
host
Submit a job from a UNIX host and run the job on a Windows
host
Specify the domain\user combination that is used to run a job
on a Windows host
Schedule and track jobs that are submitted with either a Windows
or UNIX account as though the jobs belong to a single user
LSF supports the use of both single and multiple Windows
domains. In a multiple domain environment, you can choose one domain
as the preferred execution domain for a particular job.
Existing
Windows domain trust relationships apply in LSF. If the execution
domain trusts the submission domain, the submission account is valid
on the execution host.

This feature works with a uniform user name space. If users
at your site have different user names on UNIX and Windows hosts,
you must enable between-host user account mapping.
This feature does not affect Windows workgroup installations.
If you want to map all Windows workgroup users to a single Windows
system account, you must configure between-host user account mapping.
This feature applies only to job execution. If you issue an
LSF command or define an LSF parameter and specify a Windows user,
you must use the long form of the user name, including the domain name typed
in uppercase letters.
