LFC for VO SBGrid (used by WeNMR)

lfc.pd.infn.it is a Central LFC used for VO SBGrid only, in order to execute lcg-* commands to OSG SE supporting that VO. SBGrid is a VO used by WeNMR to submit jobs to OSG sites.

Management instructions

Because of possible problems with upper case in the word SBGrid (this step was necessary in ui-wenmr, otherwise voms-proxy-init gave errors), a copy of this directory was done after installation:

 cp -r /etc/grid-security/vomsdir/sbgrid /etc/grid-security/vomsdir/SBGrid 

In case SBGrid VOMS parameters change (see https://hpc.sbgrid.org:8443/voms/SBGrid/Configuration.do), and therefore a new yaim configuration is needed, remember to repeat that command.
