ldapsearch -x -h lxb0738.cern.ch -p 2135 -b "mds-vo-name=local, o=grid"

The local GRISes running on Computing Elements and Storage Elements

In LDAP, a special attribute objectClass is defined for each directory entry

At each site, a site GIIS collects information about all resources

ldapsearch -x -h lxb0738.cern.ch -p 2135 -b "mds-vo-name=LCGCERTTB2P, o=grid"

ldapsearch -x -h lxb0738.cern.ch -p 2135 -b "mds-vo-name=local, o=grid" 'objectClass=SiteInfo' SiteName
