grid-mapfile2dcache-kpwd is used to synchronise the Gridmap file typically used by Globus utility's to map certificate distinguished name to local user group and identity. Dcache must import this user to VO table.

The following script should be placed in the directory "/etc/cron.hourly" I suggest the name "grid-mapfile2dcache-kpwd"

#!/bin/sh
/opt/d-cache/bin/grid-mapfile2dcache-kpwd

Set correct permissions on cron job

chmod 755 /etc/cron.hourly/grid-mapfile2dcache-kpwd
