Administering Platform LSF - SAS

User Account Mapping
Chapter 38
Authentication
LSF allows user account mapping across a non-uniform user name space.
By default, LSF assumes uniform user accounts throughout the cluster. This
means that jobs will be executed on any host with exactly the same user ID
and user login name.
The LSF administrator can disable user account mapping.
For information about account mapping between clusters in a MultiCluster
environment, see the Using Platform LSF MultiCluster.
Configuring user-level account mapping (.lsfhosts)
1 Set up a hidden .lsfhosts file in your home directory that tells what
accounts to use when you send jobs to remote hosts and which remote
users are allowed to run jobs under your local account. This is similar to
the .rhosts file used by rcp, rlogin and rsh.
2 Specify each line in the form:
host_name user_name [send|recv]
MultiCluster
Example 1
where send indicates that if you send a job to host host_name, then the
account user_name should be used, and recv indicates that your local
account is enabled to run jobs from user user_name on host host_name.
If neither send nor recv are specified, your local account can both send
jobs to and receive jobs from the account user_name on host_name.
Lines beginning with ‘#’ are ignored. A plus sign (+) in the host_name or
user_name field indicates any LSF host or user respectively.
3 Set the permission on your .lsfhosts file to read/write only by the
owner. Otherwise, your .lsfhosts file is silently ignored
The cluster name can be substituted for host_name in a MultiCluster
environment. For more information, see the Using Platform LSF
MultiCluster.
For example, assume that hostB and hostA in your cluster do not share the
same user name/user ID space. You have an account user1 on host hostB
and an account ruser_1 on host hostA. You want to be able to submit jobs
from hostB to run on hostA. Set up your .lsfhosts files as follows:
On hostB:
% cat ~user1/.lsfhosts
hostA ruser_1 send
On hostA:
% cat ~ruser_1/.lsfhosts
hostB user1 recv
