Platform LSF Reference Version 6.2

Environment Variables
Platform LSF Reference
291
Description
Set during LSF installation or setup. If you modify this parameter in an existing cluster,
you probably have to modify passwords and configuration files also.
Windows or mixed UNIX-Windows clusters only.
Enables default user mapping, and specifies the LSF user domain. The period (
.)
specifies local accounts, not domain accounts.
◆ A user name specified without a domain is interpreted (on a Windows host) as
belonging to the LSF user domain
◆ A user name specified with the domain name of the LSF user domain is not valid
◆ In a mixed cluster, this parameter defines a 2-way, 1:1 user map between UNIX user
accounts and Windows user accounts belonging to the specified domain, as long as
the accounts have the same user name. This means jobs submitted by the Windows
user account can run on a UNIX host, and jobs submitted by the UNIX account
can run on any Windows host that is available to the Windows user account.
If this parameter is undefined, the default user mapping is not enabled. You can still
configure user mapping at the user or system level. User account mapping is required to
run cross-platform jobs in a UNIX-Windows mixed cluster.
Where Defined lsf.conf
Default
◆ If you upgrade from LSF 4.0.1 or earlier, the default is the existing LSF user domain.
◆ For a new, Windows-only cluster, this parameter is undefined (no LSF user domain,
no default user mapping).
◆ For a new, mixed UNIX-Windows cluster, the default is the domain that the
Windows installation account belongs to. This can be modified during LSF
installation.
