In order to restrict the search to a specific objectclass, a filter of the form ’objectclass=<name>’ can be used.
By specifying a list of attribute names, the reply is limited to the value of those attributes for the corresponding
objectclass, as is shown in the next example. A description of all objectclasses and their attributes to optimize the
LDAP search command can be found in Appendix A.
Example 7.12
(Getting information about the site name from the GRIS on a Computing Element)
$ ldapsearch -x -h lxn1181.cern.ch -p 2135 -b ”mds-vo-name=local, o=grid” ’objectclass=SiteInfo’
siteName
version: 2
#
# filter: objectclass=SiteInfo
# requesting: siteName

# lxn1181.cern.ch/siteinfo, local, grid

siteName: CERN-LCG2
# search result

By adding the -LLL option we can avoid the comments and the version information in the reply.
$ ldapsearch -LLL -x -h lxn1181.cern.ch -p 2135 -b ”mds-vo-name=local, o=grid” ’objectclass=SiteInfo’
siteName
dn: in=lxn1181.cern.ch/siteinfo,Mds-Vo-name=local,o=grid
siteName: CERN-LCG2

T HE SITE GIIS

site).
For a list of all sites and all resources present, please refer to:
