NAME

       usermapping - user mapping entry file format

DESCRIPTION

       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.

       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 qconf(1) -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 qconf(1).

FORMAT

       A user mapping entry contains two parameters:

   cluster_user
       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.

   remote_user
       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.

EXAMPLE

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

       cluster_user   peter

       remote_user    peter,[@linux=pet1],[fangorn=peter1]

       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.  hostgroup(5) to obtain
       for more information about that.
