The LCAS/LCMAPS GT4-interface for Globus GridFTPd, Gatekeeper and GSI-OpenSSHd and gLExec all share the LCMAPS framework as their mapping back-end. It can be configured to use the SCAS client LCMAPS plug-in. This will contact the SCAS service to trigger an authorization decision and, on a positive result, return a mapping result. This will then be input for the LCMAPS user mapping back-end of gLExec to continue.
Installation
Add the scas-client plugin to the set of RPMs on your machine. The SCAS client LCMAPS plug-in has a requirement on the SAML2-XACML2 C Library.
Configuration
Configure the LCMAPS You would add to /opt/glite/etc/lcmaps/lcmaps.db or /opt/glite/etc/lcmaps/lcmaps-glexec.db:
scasclient = "lcmaps_scas_client.mod"
" -capath /etc/grid-security/certificates/"
" -endpoint https://graszaad.nikhef.nl:8443"
" -resourcetype wn"
" -actiontype execute-now"
and the following policy execution flow at the end:
# policies glexec_get_account: verify_proxy -> scasclient scasclient -> posix_enf
Note: This example assumes a verify_proxy and posix_enf plug-in to be configured in the same lcmaps.db file.
More information
To test your setup then you can find more information on the page for Debugging hints.
