OSG BDII (is.grid.iu.edu:2180 > lcg-bdii.cern.ch:2170)
- is.grid.iu.edu:2170 (OSG) - Top level BDII for OSG
- is.grid.iu.edu:2180 (WLCG) - Site level BDII for CERN's top level BDII
CERN pulls data from is.grid.iu.edu:2180 every few minutes according to this script > http://grid-deployment.web.cern.ch/grid-deployment/gis/lcg2-bdii/dteam/lcg2-all-sites.conf [David Collados]
New records and changes in existing records normally show up on lcg-bdii.cern.ch within a few minutes, whereas records deleted at the source are retained for 24 hours, with any Status attributes set to Unknown. [Maarten Litmaath]
Can CERN pull data from port 2170 so that we don't have to provide 2 instances? "No as the suffix used in the dn is Mds-Vo-name=local,o=grid, so all entries will be rejected due to the recursion protection feature." [Laurence Field] But, once we move to OpenLDAP 2.4, we can use its alias feature to overcome this problem.
To create an 'alias' you need to add the following to the slapd.conf file. (For OpenLDAP 2.4)
# Load the required modules
# Configure the alias
