ARC CE Hints

Mapping to pool accounts

Argus in combination with lcmaps can be used to map DNs to pool accounts. In the [gridftpd] section of /etc/arc.conf include the following:

unixmap="* lcmaps liblcmaps.so /usr/lib64 /etc/lcmaps/lcmaps.db voms"
unixmap="nobody:nobody all"

where /etc/lcmaps/lcmaps.db is

path = /usr/lib64/lcmaps

verify_proxy = "lcmaps_verify_proxy.mod"
                    "-certdir /etc/grid-security/certificates"
                    "--discard_private_key_absence"
                    "--allow-limited-proxy"

pepc = "lcmaps_c_pep.mod"
            "--pep-daemon-endpoint-url https://lcgargus02.gridpp.rl.ac.uk:8154/authz"
            "--resourceid http://authz-interop.org/xacml/resource/resource-type/arc"
            "--actionid http://glite.org/xacml/action/execute"
            "--capath /etc/grid-security/certificates/"
            "--certificate /etc/grid-security/hostcert.pem"
            "--key /etc/grid-security/hostkey.pem"
