.SH NAME
usermapping \- user mapping entry file format
.\"
.SH DESCRIPTION
.PP
A usermapping entry is used to define alias names for a cluster 
user. The user's name known by the scheduling system is known as the
cluster user. If the cluster user doesn't match the user account
name on an execution host, the usermapping feature can solve the
problem.
.PP
Each line in the usermapping entry file specifies a user name and
the host(s) where he has an account. 
.PP
A list of currently configured user mapping entries can be displayed 
via the
.M qconf 1
\fB\-sumapl\fP option. The contents of each enlisted user mapping entry 
can be
shown via the \fB\-sumap\fP switch. The output follows the
.I usermapping
format description. New user entries can be created and existing can be
modified via the \fB\-aumap\fP, \fB\-mumap\fP and \fB\-dumap\fP options to
.M qconf 1 .

.SH FORMAT
A user mapping entry contains two parameters:
.SS "\fBcluster_user\fP"
The cluster_user keyword defines the cluster user name. The rest of
the textline after the keyword "cluster_user" will be taken as cluster
user value.

.SS "\fBremote_user\fP"
The user name on an execution host. Please note that the value for this
attribute might be overwritten for a certain hostgroups or single host.
Find an example below.

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

.PP
cluster_user   peter
.PP
.PP
remote_user    peter,[@linux=pet1],[fangorn=peter1]
.PP
The entry will map the user peter which is defined in the cluster system to
the user peter on all hosts in the cluster except for all hosts which
are referenced in the hostgroup @linux. For all these hosts the user will be
mapped to pet1. For the host fangorn the remote user will be peter1.
.M hostgroup 5
