USERMAPPING(5)

NAME
usermapping - user mapping entry file format

DESCRIPTION

A usermapping entry is used to define alias names for a cluster user. The users name known by the sheduling system is called cluster user. If the cluster name doesn't match the user account name on an execution host, the usermapping feature can solve the problem.

Each line in the usermapping entry file specifies a user name and the host(s) where he has an account.

A list of currently configured user mapping entries can be displayed via the -sumapl option. The contents of each enlisted user mapping entry can be shown via the -sumap switch. The output follows the usermapping format description. New user entries can be created and existing can be modified via the -aumap, -mumap and -dumap options to

A user mapping entry contains at least tree parameters:

cluster_user keyword

name
    The user name on an execution host.

hostname
    The name of the host where the user specified in name has an account. If The first character of the hostname is a "@" sign the name is used to reference a

EXAMPLE
This is a typical user mapping entry for a cluster user mapping:

cluster_user office

alice wonderland, realworld, @office2

The entry will map the user office which is defined in the cluster system to the user alice on the hosts wonderland and realworld. The "@" sign is used to reference a host group. So the user office is mapped to alice on all hosts specified in the host group office2. Please see to obtain for more information about that.
