The Local Centre MAPping Service (LCMAPS) is a security middleware
component that processes the users Grid credentials (typically X.509
proxy certificates and VOMS attributes) and maps the user to a local
account based on the site local policy.
This package contains the LCMAPS jobrepository plug-in, which stores
credentials and the resulting account mappings into a relational
database. This plugin will link up all the known in-process information
from LCMAPS core memory and store it in a database. This plug-in uses
ODBC (http://en.wikipedia.org/wiki/ODBC) to connect to the database.
The current state of the mappings between various credentials and Unix
accounts is stored in an open database on disk, but this information can
change over time through (regular) system administrative interventions.
By using this plugin, this state is additionally preserved in a
relational database with the added benefit of being accessible by other
systems, e.g. GridSAFE and build-up an easy to backup historic view on
the mapping state.
